Site News (2007-2009)

May 16, 2007 – What’s Up With The Changes?

As many of you have no doubt noticed, I have scaled back the site to focus on information regarding the various home TRS-80 models and emulators and utilities related thereto. I know that people are curious as to why the dramatic shift was made.

The bottom line is that the site takes a massive commitment, and the time, energy and money would be better spent on my family. It has gotten exponentially harder and harder to maintain the site each year. When it comes down to it, family is the most important, and shedding myself of the burdens brought on from the site will be a welcome relief.

The sites original goal was to preserve the memory of these machines and to provide help to those who wished to relive their experiences with their first computer. I have converted people’s long lost papers and records (and the memoirs of their deceased loved ones). The site has enabled people to relive their simpler days. I never charged anyone a single penny for any thing I ever did, even when blank DVD’s, blank floppies, and postage were involved, and did it all gladly.

I think the site has worked wonders to preserve the TRS-80 through the hard work of many people who have written software to let us image and archive what seems to be rapidly degrading disks and cassettes, and to run those images on modern hardware. While there are so many people to thank for their help, and I am loth to even do so with the fear of forgetting anyone, there are 3 main people (in this category) I found to be personally helpful to me in this endeavor.

First, is Matthew Reed. At a time when there was no freeware utility to read a TRS-80 disk into DSK format using modern hardware, Matthew rode to the rescue by writing READDISK and releasing it as freeware. Without this utility there would have been no widely distributable way for people to image TRS-80 diskettes.

Matthew also prepared, in my opinion, the finest DOS and Windows TRS-80 emulators. Matthew always took my bug reports, suggestions, and wishes to heart and Matthew’s latest emulator remains the only TRS-80 emulator which can emulate a TRS-80 printer. An example of something which Matthew had incorporated as a site aid was “Autoboot”, which enabled me to mount a DSK image without having to know whether the disk was Model 1, 3, or 4. This featured stopped me from having to go to Configure, and cycling through each model, one by one, if a hard reboot on a DSK image produced nothing more than an empty screen, and the list of features which Matthew put into his emulators in an effort to help me out does not stop there.

Second (but, again, in no specific order) is Tim Mann. While Tim’s efforts are all his own, his preparation of the drivers for the Catweasel floppy disk controller card enabled the reading of non-standard and problematic disks. Disks which I would occasionally receive proved excellent fodder for the utility, and Tim was always willing to take bug reports and feature requests.

Third (but, again, in no specific order) is Knut Roll-Lund. Knut is doing for cassettes what Tim and Matthew did for diskettes. Knut’s WAV2CAS utilities enabled the archiving of cassettes. When Knut finished his Level II compatible converter (500 baud), I came up with WAV’s for Level 1 cassettes (250 baud). Knut worked hard to create a Level 1 converter, just as I wound up with Model III tapes (1500 baud and NOT straight ASCII). Knut has since been working on utilities which attempt to determine if a SYSTEM or BASIC tape was not a good dump. The day when Knut manages to integrate an audio capture program which then monitors volume levels, converts to CAS, and test the result for validity, should be a considered a very significant day in the TRS-80 world.

There are also those who have donated hardware (such as disk drives and cassette players – both of which I can easily and quickly wear out) and other help. My thanks go out to these people as well.

I intend to continue with the site, adding information as I find it. I will certainly post any updates as to emulators or tools to read TRS-80 disks and cassettes, and I hope those who develop these fine tools keep doing so with great gusto. I also intend to continue to add any links for any TRS-80 related sites which are out there or which may show up.

May 18, 2007 – eBay

With any luck, I will be able to go thru my TRS-80 collection and start listing eBay auctions this weekend. What I hope to put up first (probably because they are the easiest) is the fairly heavy TRS-80 related Sams Computerfacts collection, and ALL of my original diskettes. These two will likely be broken into different traunches to enable easier shipping. I also hope to list some *working* Model 100’s, *working* Pocket Computers, and manuals. In the future, I will try to gather all the pieces of Model I’s I have lying around, assemble and test them, and get some *working* Model I’s on eBay as well.

May 23, 2007 – Site History Online

I have added the site’s story to the Personal Stories link. It is very much a work in progress.

May 29, 2007 – Status of DVD’s of PAPER downloads

First, I would like to thank everyone who sent me emails. Emails fell into three categories – 1) sincere thanks for what I had done for the TRS-80, 2) kind offers to host/mirror, and 3) kind requests for DVD’s.

With regard to # 3, I did not respond to any of them, prompting some people to email a second and third time. As most of you know – ignoring emails is not what I do, but I had very little to say. So, I thought a news item may be best …

As many of you know, some individuals had been selling (and some continue to currently sell) the DVD’s on eBay, and taking in ridiculous amounts of money from doing so. When one individual managed to sell each individual DVD of the 4 DVD set for $30+ per disk (his donation to the site for all 4 + shipping was $20), I took down the DVD link and ceased making them.

In fact, this person found it so profitable to copy and sell the DVD’s, that he was simply making copies and continued to list them on eBay (his auctions show lots of 10, per disk). He had initially listed the DVD’s as a harmless ‘I didn’t want these disks, so I am going to just sell them for 1 cent’, but once the eBayers, in their infinite wisdom, paid him 30+ per disk, he started making copies and bulk selling them … and that’s a different story.

So, while I appreciate all the kind words and support, I doubt I will ever make the DVD’s again if this is how it is going to go — so no need to email asking for them.

May 31, 2007 – 80 Micro Pages

It dawned on me that since none of the 80 Micro pages contained downloads, there was no reason to remove them. I have restored all the 80 Micro pages, as well as the 80 Micro Table of Contents search engine.

June 3, 2007 – Next eBay Auctions

Although it will take me some time, I believe the next eBay auction will be for all of my original TRS-80 disks. They currently take up 3 of those hard plastic disk holders (which I envision I will include).

June 4, 2007 – Cleanup

I have cleaned up the old pages and have restored them without links. Now they are cover scans, but at least the info is back up.

Also up are the emulator pages and transferring pages.

June 7, 2007

Thank you all for your continuing supporting emails.

Three questions continue to show up, and I would like to at address them here:

1. I have X software/magazine/manual, do you still want it? Yes, yes, yes. Please continue to send me scans of books, magazines, manuals, etc. Just yesterday, (i) I finished processing a scan of the 1978 Tandy Computer catalog (which contained exactly 1 page of TRS-80’s out of 52 pages!), (ii) the CopyCat II instruction sheet was scanned, and (iii) today I received a scan of the Model I Double Density Disk System Owners Manual. If you have it, please send it. If I do ever make DVD’s available of the paper downloads, newly acquired and scanned items will be on it.
2. Can I have a DVD of the software downloads? Yikes. As stated below, and while I do appreciate the requests and the financial offers which have come along with them, I have never and will never send out the software files on DVD.
3. I just got a X at a garage sale, and went to find the hardware manuals for it, but the manuals seem to be gone.. If you have a specific hardware manual in mind, please send me an email with the details and I will do my best to help you out.

June 19, 2007

In case you have been wondering what I have been up to, other than the eBay auctions, of course, I have been adding ‘ad’ scans for the former library and have also won another TRS-80 book on eBay. I am thinking about restoring the Software section, but without links, so it can act as a library/lookup for TRS-80 software information.

New TRS-80 Paperback Book Hits The Shelves

The following is an announcement by Theresa Welsh about her new book.

Priming the Pump: How TRS-80 Microcomputer Enthusiasts Helped Spark the PC Revolution
355 pages, with full Index and over 100 illustrations
Paperback Edition. ISBN 0780979346804
Only $19.95

This is the first book to capture the unique era of the late 1970s and early 1980s, when personal computing was just getting started. David and Theresa Welsh were part of the community of small software entrepreneurs and personally knew many of the principle players whose accomplishments are the stuff of legends.

Some of What’s in this One-of-a-Kind Book:

• Steve Leininger, hired away from Silicon Valley by Tandy Corp., worked alone amid the grimy surroundings of an old Fort Worth saddle factory and built the prototype TRS-80; the final development cost was less than $150,000.
• John Roach, Tandy’s product manager, got an agreement from Charles Tandy to build 3500 units after Leininger demonstrated the prototype; this was exactly the number of stores they had — Roach figured if no one bought the computers, at least the stores could use them. Don French, a true believer, predicted they’d sell 50,000 the first year and urged the company to gear up the factory for mass production. Tandy managers, thinking they could never sell that many, were surprised when, in the weeks after the introduction, the Tandy switchboard was paralyzed with over 15,000 calls from people wanting to order a TRS-80. In the first year, over 250,000 people went on waiting lists to buy a TRS-80!
• Tandy contracted with Randy Cook to create a Disk Operating System (TRSDOS) for the TRS-80 Model I and III, which would support floppy disk drives. The company agreed Cook would retain ownership of the code. But Cook, believing Tandy violated the agreement, created a rival DOS which he sold through his own company. Tandy managers found Cooks’ name embedded in the TRSDOS code.
• TRSDOS replacements appeared – five of them – and programmers made up their own homespun magazine ads touting their products great features and attacking their rivals’ products in the pages of magazines like 80 Micro, the most popular of many publications devoted to the TRS-80. e.g. Wayne Green, publisher of popular computer magazines, promised to “editorially break” Radio Shack because they would not carry his 80 Micro magazine in their stores; his magazine column often lambasted Radio Shack CEO John Roach.
• Bill Schroeder, a successful businessman, bankrolled Logical Systems, Inc. and sold Tandy on LDOS as the company-sponsored TRSDOS replacement. A state-of-the-art headquarters and good money followed the lucrative contract, but once he sensed the coming demise of the TRS-80, Schroeder simply shut down his company.
• Scott Adams created popular Adventure games for the TRS-80 and other early microcomputers, became a celebrity in the magazines, but produced too many game cartridges for a computer that died in the marketplace.
• Along with microcomputers, home robots were hot. Meet the robots of the 1980s – and the man who said we were all going to have mechanical men in our homes by the year 2000. Unlike microcomputers, robots just didn’t catch on.
• A notorious scam artist preyed on the gullibility of microcomputer enthusiasts, destroying the Southern California Computer Society with a Ponzi scheme, then bilking TRS-80 owners out of thousands of dollars with magazine ads from a bogus company called World Power Systems showing phony products.

Here is the real story of the first microcomputers, based on the Welsh’s personal experiences selling TRS-80 software and our interviews with amazing microcomputer pioneers.

Visit the book website at http://www.microcomputerpioneers.com/ to read excerpts.

At present, the book is available only from the Welsh’s, but it will be listed on amazon.com in the coming few weeks.

July 3, 2007 – Updated Emulator, ReadDisk, and More!!

BIG NEWS! Matthew Reed has updated his Windows emulator to v1.16 and his fantastic READDISK utility to v2.1, all under a brand new domain name of www.trs-80emulators.com.

I have updated all the links here, or you can go directly to his web site and download the software there.

There have been many bug fixes and tweaks, including:

• Revamping the keyboard handling to work better with CP/M
• Autostarting now resets the pause state; and
• TRSDOS 6.01.00 now autostarts.

Registration of the emulator (I get NO share or incentive for your registrations) provides you with:

• Multiple types of high-resolution graphics boards
• Orchestra 85/90 music generation
• Several types of real-time-clocks
• Up to 1of additional memory (in Model 4 mode)
• Virtual hard drive support; and
• Epson FX-80 compatible printer emulation

This is the emulator I use in maintaining the site.

July 20, 2007 – Updated Cassette Utilities from Knut Roll-Lund

As some of you may know, what Matthew Reed and Tim Mann did for diskettes, Knut has done for cassettes.

Knut has now refined his wonder cassette utilities and has released a major major upgrade. The new version has the following features/improvements:

• Reads LEVEL 1, LEVEL 2 and MODEL III High-Speed
• Reads tapes with more than one “file” and they can be any combination of the above types.
• Decodes the data to verify the contents and displays the result
• The LEVEL 1 and LEVEL 2 decoding is better (now it is probably better than the original)
• Improved Model III High-Speed decoding, some special typical errors are handled too.
• Dropout problems are almost gone, as long as there is data wav2cas can read it.

There are currently a few outstanding issues:

• Will not read tapes that have very bad timing
• Doesn’t like ringing so don’t record with too high volume.
• Will probably have problems with system tapes output directly by EDTASM, because EDTASM inserts pauses.
• You should use at least 22,050 samples per second when recording.
• While it understands basic and system tapes, it does not yet understand assembly from EDTASM or Scripsit documents.
• Disassembly is not yet implemented.
• No documentation or help file is supplied.

July 28, 2007 – MicroDOS

I am in the process of going thru a bunch of disks I have received, and I must say that microDOS is possibly the most annoying Operating System ever made. Apparently, it is designed to be incompatible with every other DOS, and their recommendation for getting programs on/off disks with their DOS is to CSAVE and CLOAD. What a nightmare.

July 30, 2007 – Updated Model Pages

The main information on the site is under the Models page. In it I have been augmenting each and every catalog number and peripheral available from Radio Shack for the Model 1/2/3/4. As I continue to scan catalogs (which have been posted), I continue to update these pages with new information and pictures.

January 2, 2008

Sorry for the lack of news. The reason I had stopped posting news is that every news item I posted came back with immediate “negative” emails and/or forum posts (although I always wondered why people would come to the site just to complain). I probably should have realized earlier that people who are going to complain are going to do it no matter what, and that’s why the ‘delete’ key was created, so I hope to resume posting news.

• Small sized single EXE program, no external files are needed
• Running on standard WIN32 environment (Windows 95 and up)

System requirements & installation:

• The program was written and compiled in a special way with the “Microsoft Visual C++ 2005 Express Edition” using only standard WIN32 API interface, not referring to any external run time library. It runs from Windows 95 to the latest windows releases. The program in standard mode consumes insignificant system resources, however in “full speed” mode it eats up one processor.
• No special installation is needed, the files should be extracted from the downloaded zip package into any directory, and FASTZ80.EXE can be run.

Basic features of the simulated hardware:

• Machine cycle accurate instruction set of Z80 processor is implemented
• Undocumented instructions are implemented. See “The undocumented Z80” for details.
• The content of ROM & ROM Extension is coming from the original HT1080Z, but it can be configured
• Sound chip is not emulated, however it was a special addition in HT1080Z
• The first version of the original machine contained only 16 kByte RAM, this implementation contains 48 kByte
• OUT instruction has no effect
• IN instruction results reading value FF, except port FF, where bit 7 is simulated as the TAPE input
• NMI is supported (can be triggered from menu), however maskable interrupt (INT) is not
• Includes two Z80 engine, one contains some simplifications for reaching better performance. See “Tuning the emulator”.

March 25, 2008 – New Utility by Knut Roll-Lund

Knut, master of TRS-80 cassettes, has done it again with the release of his new utility, PLAY CAS. While this utility can do a lot of things, its main function is to allow you to plug your TRS-80 EAR connector into your PC Soundcard headphone output, and turn your PC into a TRS-80 cassette player. Once hooked up in this manner, the utility will play a CAS file stored on your PC into the TRS-80 plug, so your TRS-80 thinks it is getting input from a cassette, but its really from the PC.

Play CAS checks the CAS to determine whether its a Level 1, Level 2, or Model III Highspeed image.

Download and instructions are available on the Media Conversion page.

August 13, 2008 – Anyone have a spare Model I?

Do you have a Model I that you would like to see go to a really important good home?

The American Museum of Natural History in New York City is looking for a Model I in good physical shape to tour with an upcoming traveling exhibition. The tour would last 10 years which is why they are interested in acquiring the Model I instead of borrowing it. At the end of the tour they will be donating it to another non-profit exhibition.

Similar to the old Billy Crystal Saturday Night Live skit, it is much better for the Model I to look good than to feel good. While it would be nice if it worked, they are more interested in a Model I which is physically good looking, as it will be on display. A non-working Model I is fine by them.

The Model I does not need to have, but can have, an expansion interface and floppy disks. That would augment the exhibition, but they are really after the Monitor / Keyboard.

If you can donate your Model I, please let me know and I will put you in direct contact with them. They can, and will, provide a letter of donation for the IRS (although the donor would have to provide the value).

August 25, 2008 – Two Model I’s to Sell for Local NJ Pickup Only

Two working Model I’s (or so I am told) for sale for local pickup, one manufactured in 1978, the other in 1980. I believe each has its own expansion interface.

The seller has a lot of stuff, including a service manual for the Model 1, game tapes [if she can find them] & other manuals. She has 5 disk drives total.

She does not want to ship them. Contact me, and I will forward the offers on. Pickup is in Bergen County NJ.

Most of the archived copies of SoftSide are of a lower quality due to them having been scanned by the donor in Black and White Bitmap (cardinal sin #1 in scanning).

January 28, 2009 – New DSK/DMK Utility – PDRIVE Finder

Phil Ereaut has released PDRIVE Finder v0.5.

PDRIVE Finder will display the PDRIVE settings of any DSK or DMK image which was “formatted” by NEWDOS/80. Great for data disks where you cannot figure out what PDRIVE settings can be used to access the data.

January 28, 2009 – New DSK/DMK Utility – Emulator File and Sector Display

This utility will display the characteristics of a DSK or DMK image, as well as act as a HEX/ASCII sector and file display/editor utility.

Download Emulator File and Sector Display v9.1 HERE

Update: Phil Ereaut has advised that this version is faulty. A replacement version is found under February 1, 2009 news. This download has been removed.

February 1, 2009 – New DSK/DMK Utility – Emulator File Type and Format Finder

Phil Ereaut has released his Emulator File Type and Format Finder 2009 v1.0.

This utility analyzes DSK and DMK files and shows filename, DOS, PDRIVES, Tracks, Density, Sides, Sec/Cyl and SPG. Will also note where Track Sectors start at 1.

February 4, 2009 – New DSK/DMK Utility – Emulator File Read and Copy

Phil Ereaut has released his Emulator File Read and Copy 2006 v3.1

This program reads .Dsk files, and displays the disk filenames in a list box. Clicking on a file, allows the file to be saved to a PC folder. It can be used just to view the Files on a .Dsk, if you dont want to copy the files.

It doesn’t always work, but it has definitely helped me extract files from DSK images which the emulator would not recognize.

March 2, 2009 – Problems with WordPress

UPDATE: I found my answer after a LOT of searching.

If anyone out there is familiar with WordPress and PHP errors, please email me. WordPress is giving me Internal Error 500 when I try to post or view or edit pages. No other functions (news, media, links, etc) are affected – only “pages”. Thanks!

March 3, 2009 – Still Having WordPress Problems

I suspect that the site is too big for WordPress. Although I had solved the problem yesterday, it re-emerged as I continued to port pages over. I was able to move about 2/3 of the entire site before WordPress’ capabilities were exceeded. I am still ‘locked out’ of page functions with a “500 Internal Error” on the php code, but I can transition the site back to the old format, and still keep WordPress for the news. Thank goodness I never implemented anything in WordPress without implementing it in my HTML first.

The good news is that the attempted WordPress port spurred me to add magazine details, increase the cover scans, and clean things up. Those benefits will continue.

Of course, I do continue scanning, and have some new stuff on the way.

March 4, 2009 – WordPress Limitation Workaround

In addition to the php.ini at 25MB (didn’t work alone, but left it there anyway), I added a line to HTACCESS which some stated solved some PHP5 processing problems on 1and1 hosted sites. This gave me access to the ‘pages’ functions again. I realized that 1/2 of the pages were single magazine pages (showing the cover, giving issue information/stats, and setting out the tables of contents). I have realized that if I port the entire site over (or as much as can go … I don’t think my SQL pages can go) but leave the single magazine pages as they were, I should not hit the WordPress limitation.

March 27, 2009 – WordPress Done (I Think)

• Although some pages require a little tweaking (most notedly, those magazine issue pages which were backed out of WordPress due to WordPress limitations), I believe all of the pages that are going to be transitioned to WordPress have been transitioned.
• I have updated the H&E Computronics page to provide for larger cover images, additional issue details, and, of course, the associated Tables of Contents from each of the issues.
• Finally, the NEWDOS/80 Page is now complete. Of course, if anyone has additional information, tips, hints, patches, etc., I would love to hear!

I apologize for the serious lack of updates to the site, but things at work have been fairly intense. The following has been added to the site:

• Backing Up Tape FS1
• Concatenating TABLE/CIM into DISASM/CMD
• Modifying ORCH-85 and PIANO-85 to Take Command File Inputs
• Disabling Passwords in DOSPLUS 3.4
• Forcing VERIFY in DOSPLUS v3.4
• Undocumented Z-80 Opcodes

May 6, 2009 – Update to Matthew Reed’s TRS32 Emulator

Matthew Reed, creator of the fantastic TRS32 (Model I, III, 4 emulator for Windows) has just released an update to v1.19.

Changes include:

• Corrected problem with flickering and incorrect colors while in full-screen mode
• Fixed problem with double-wide status in Model I mode (Thanks to Al Wallace)
• Added a new Level I, Model III mode

May 5, 2009 – Mythical Model III, Level I Found

David Cooper has located, with the aid of John Benson, a Level I Model III, and has taken pictures of the insides as well as dumped the ROM. David wrote:

Well, folks, the Model III, Level I ROM is no longer an extinct species! I have purchased a Model III, Level I machine and have made an image of it’s ROM.

Before I continue, please allow me to thank John Benson of Australia for locating this machine. He notified me of the machine for sale so that I could purchase it. Without his locating the machine, I would never have been able to obtain the machine and image the ROM.

It appears that the ROM is a 4K ROM, even though it’s plugged into the ROM A socket on the Model III motherboard (which supports 8K ROMs). I say this because when I read the ROM, the A12 line *appeared* to be ignored. This makes sense because Model I, Level I ROM was only 4K. But, it’d be nice to see a datasheet on this ROM. I couldn’t find one anywhere. The chip number is SCM91616P, which is a Motorola ROM.

May 11, 2009 – Model I / Free for Pickup

TRS-80 Model I with expansion interface, floppy drive, cassette recorder, and Line Printer VII (with complete dust covers), as well as TRS-80 power strip, joystick, and a bunch of manuals and books, are free for pickup

As for the working status, here’s what I am told: The Model I does power up and does operate, but there may be an issue as the letters not all right. A test program ran. The E/I may or may not work (hard to tell), so it was not possible to test the floppy or the printer.

The items are in Auburn, California (Sacramento area).

As always, first come, first served (through emailing me only – not through usenet postings). If you are willing to pickup, please let me know, and I will put you in contact with the donator.

May 19, 2009 – New 80 Micro Cover from Horacio

Horacio has provided Volume 100 of 80 Micro, and the data for Issue 100 has been added to the 80 Micro 1988 web page, and the searchable Magazine Table-Of-Contents database.

This brings the count up to 100 out of 101 with only one (1) issue from 1998 remaining.

Thank you Horacio.

May 19, 2009 – Last 80 Micro Cover from Horacio

Horacio has finished scanning the 80 Micro’s!!!! The data for Issue 101 has been added to the 80 Micro 1988 web page, and the searchable Magazine Table-Of-Contents database.

Thank you for all your hard work, Horacio.

May 19, 2009 – Beta Testing New Search Function

With Horacio having finished scanning the rest of the 80 Micro’s, and with Thomas McNair busily scanning missing SoftSide’s, I have used my extremely limited knowledge of HTMLized SQL to expand the (now deleted) “80 Micro Magazine Search Page” to a “TRS-80 Magazine Search Page”. Right now it can accept Softside or 80 Micro (through some fairly sloppy coding which will NOT scale well once additional types of magazines are added), and I have added SoftSide Issue 39 to the NEW Database.

If anyone is interested in helping convert tables of contents to lines of database code, please contact me. It will basically involve typing in the tables of contents in a specific way, and you can do as little or as much as you want.

May 8, 2009 – LNW Research Expansion Board

A site visitor from Ann Arbor, Michigan has found a LNW Research Expansion Board, and many, if not all of the parts to go into the board.

He is asking for $50 (which includes U.S. shipping & handling). If you are interested, please contact me.

June 13, 2009 – Fake Ad from Mike Yetso

Mike Yetso provided a fake ad, which used to be on a 24×36 glossy photoprint (which he no longer has). He writes:

This is a real ad. Well, it was real, but it wasn’t to the general public. It was for an industry magazine. If I remember right, it was called ‘The Yellow Jaundice’. I think it was a ‘trade journal’ that dealt with sunday newspaper supplements. Anyway, every April they would make a ‘spoof’ ad. They did one with three guys standing at urinals, and one had a PC (pocket computer in those days). The ad read “The PeeWee computer that goes where you pee”, or something like that. When some people at Tandy saw it, they said if you’re going to poke fun at us, at least make it a good one. The magazine responded with “Ok, YOU do one next year”, and the ad was what was actually published in the magazine.
Tandy actually got coupons from the ad back!
If I remember right, one of the guys in the ad was Sal Greski (sp?)”

June 25, 2009 – Also updating magazine search

As I add magazine (covers) to the web site, I am also expanding the Magazine Table of Contents search with those magazines. As always, if anyone is interested in helping add magazines to the searchable index, please let me know!

June 26, 2009 – Update to Matthew Reed’s TRS32 Emulator

Matthew Reed has updated his fantastic TRS32 emulator to v1.20, this time adding Exatron Stringy Floppy emulation support (and increasing the window margin sizes to improve readability).

This is the emulator I use in maintaining the site and in addition to being one of the very few emulators out there which is Windows NT/XP/Vista compatible, it is also the only one which is updated regularly.

You can download a copy from Matthew’s web site [Link Deleted] or from the first entry on the TRS-80.com emulator page.

I heartily recommend you register the emulator [Link Deleted] (and no, I do not get a penny from that registration; it is just very very good software).

June 29, 2009 – Exatron Stringy Floppy Basic Operation

For those of you who use Matthew Reed’s TRS32 emulator and wish to make use of the ESF module, please note the following:

• The ROM esf.rom needs to be in your ROMs directory
• Exatron Stringy Floppy needs to be enabled in your configuation screen
• You need to invoke the ROM through a SYSTEM command
• For file I/O, you will need to mount a virtual wafer.

To invoke the ESF ROM use the SYSTEM command with the following addresses:

ESF Commands are:

The following commands will only work if you load the “Data I/O Program” from a wafer that came with the Stringy Floppy. To date, no wafers have been dumped. Each functions exactly the same as it does for TAPE and DISK.

July 1, 2009

Sorry about the lack of updates … I have been adding Tables of Contents of various magazines to the web site and to the searchable table of contents archive. As of now, all of my 80 Micro’s, SoftSides, Micro-80’s, Prog-80’s, H & E Computronics, and The Alternate Source have been added. The archive page shows the status of all of the magazines, and that status will update as more tables of contents come online.

Additionally, Kim Watt was kind enough to send over a box of disks and manuals, and I have been reading the disks and scanning the manuals.

July 7, 2009 – More Magazines in Search

While I continue to scan the manuals which Kim Watt kindly sent over, I have updated the searchable table of contents to include all of the 80-NW Journal and 80-US Journals, as well as all the Basic Computing (which is what 80-US turned into) I have. I do not know the last published issue, so I have flagged it as yellow (=entered all I have) rather than green (=all known issues entered).

July 9, 2009 – Three More Magazines in Search

Three more magazines have been added to the searchable table of contents: Barons Microcomputing (the few issues I had), The 8ighty (the few issues I have), and The 80 Notebook (all of them). The corresponding pages have also been updated to include the tables of contents.

July 9, 2009 – TRS-80 Virtual Floppy Disk Manager by Miguel Dutra

Miguel Dutra has released a BETA of his new Virtual Disk Manager utility for Windows. This is a small utility which allows you to access virtual TRS-80 disks at a file level, as if they were normal PC disks.

July 10, 2009 – One More Magazines in Search

TRSTimes has been added to the searchable table of contents.

By the way, for those who are uaware, all of the TRSTimes issues are downloadable.

July 11, 2009 – Terry Stewart’s Blog

For those who do not know, Terry Stewart has been spearheading the effort to get Exatron Stringy Floppy images moved over for use in Matthew Reed’s emulator. Terry has a blog [Link Deleted] on a fairly diverse set of topics, sometimes discussing TRS-80’s, but in almost all cases, involving problem solving. Terry’s blog can be found at http://www.classic-computers.org.nz/blog/.

July 13, 2009 – Another Magazine Updated

The few issues I had of the French magazine, Trace, has had its tables of contents added to the searchable table of contents. Of course, since it is in French, results which search for words (instead of, for example, by issue number, year, etc) are unlikely to show up given the incompatibilities of the international character set.

July 14, 2009 – TRS-80 Microcomputer News

I have updated the TRS-80 Microcomputer News page with bigger thumbnails and not-yet-implemented links to separate pages which will contain their tables of contents. I am slowly adding new pages (and updating the Searchable Table of Contents page to include the TRS-80 Microcomputer News. This part will be slow going.

July 15, 2009 – TRS32 Updated to v1.21

Matthew Reed has issued an interim update to his FANTASTIC TRS32 emulator. Changed in this update is:

• Added sound to the Stringy Floppy emulation
• Improved the sound used by the floppy disk emulation
• Fixed a problem with returning Stringy Floppy status
• Changed the floppy autostart order to favor the Model I
• Fixed emulated floppy disk sector not found behavior
• Added copy and paste features
• Corrected behavior of an emulated Model I without lowercase

For those who have not yet registered Matthew’s emulator, I encourage you to do so. This emulator (unlike 98% of the others) is still in development and is phenomenal. You can register at Matthew’s site.

July 16, 2009 – TRS-80 Microcomputer News

Issues 1 through 27 of TRS-80 Microcomputer News have now been added to the Searchable Table of Contents page, and their TOC’s have been added to their respective pages.

July 17, 2009 – Puget Systems

I realize this is off topic, but when you come across something really cool, sometimes you gotta mention it. Although my TRS-80 was the last system I had purchased as an assembled unit (preferring to build my own), I have been familiar with Puget Systems [Link Deleted] for a while. Puget allows you to select brands and types (A corsair TX 850 power supply or w WD Caviar SE16) rather than just generic (850 watt; 200GB Hard drive, etc). I elected to go with them and, although I have not yet received the system, every question I have asked them (and I have asked a TON) has always been met with a quick and technologically correct answer. What I just noticed, though, is their order status page. This thing not only has each component and each test they ran, but temperature logs of the system under load over time, and performance benchmarks. They also email pictures of the inside, front, and back of your computer once its built, including a thermal picture of the inside. Crazy stuff.

Oh, and for the skeptics out there, NO I am not getting any payment from them. I am just THAT impressed (kinda like the way I talk about Matthew Reed’s emulator).

July 19, 2009 – New TRS-80 Emulator by George Philips

George Philips has released v1.5 of his TRS80GP Emulator which is available for download from the emulator page.

George describes the emulator as “built primarily as a development tool for software written for real TRS-80’s and for experiments in improved emulation fidelity. It can load programs in .cas, .hex, .bas or .cmd format directly but has no disk emulation nor can use use CLOAD or SYSTEM to load .cas files (as in most normal emulators).

I would say that this ’emulator’s strength is that you do not need to set up a ROM (it is built in), import files onto DSK/DMK’s, have boot disks, etc. If you have a /CMD file or a /BAS file or a /CAS file, you would simply execute the emulator FROM A COMMAND LINE, and your program would run. No fuss.

More details can be found by running the emulator with a -? flag will also provide details.

July 22, 2009

Issues 1 through 43 of TRS-80 Microcomputer News have now been added to the Searchable Table of Contents page, and their TOC’s have been added to their respective pages.

July 23, 2009 – TRS-80 Virtual Floppy Disk Manager Updated

Miguel Dutra has released v0.2 of his new Virtual Disk Manager utility for Windows. This is a small utility which allows you to access virtual TRS-80 disks at a file level, as if they were normal PC disks.

The TRS-80 Virtual Disk Manager shows the file name, size, date and attributes of each directory item, supports reading both .DSK and .DMK image files, and allows exporting TRS-80 files to the Windows file system.

Miguel lists each possible DOS for the TRS-80 and whether or not it is currently supported, with his ultimate goal being 100% of all OS’s.

Explanations and the program can be found on the TRS-80 Disk and Tape Conversion Utilities page.

July 24, 2009 – TRS-80 Virtual Floppy Disk Manager Updated

Miguel Dutra has released v0.2.2 of his new Virtual Disk Manager utility for Windows. This is a small utility which allows you to access virtual TRS-80 disks at a file level, as if they were normal PC disks.

Explanations and the program can be found on the TRS-80 Disk Utilities page.

All issues of TRS-80 Microcomputer News have been added to the Searchable Table of Contents page.

September 13, 2009 – TRS-80 Virtual Floppy Disk Manager Updated

Miguel Dutra has released v0.4 of his command line version of his Virtual Disk Manager utility for Windows. This is a small utility which allows you to access virtual TRS-80 disks at a file level, as if they were normal PC disks.

Explanations and the program can be found on Miguel’s web site and on the TRS-80 Disk and Tape Conversion Utilities page.

September 27, 2009 – TRS-80 Virtual Floppy Disk Manager Updated

Miguel Dutra has released v0.5 of his GUI version of his Virtual Disk Manager utility for Windows. This is a small utility which allows you to access virtual TRS-80 disks at a file level, as if they were normal PC disks.

It appears that this utility can read all known TRS-80 DOS’s except for (1) CPM and (2) anything made by Percom.

Explanations and the program can be found on TRS-80 Disk and Tape Conversion Utilities page.

The new version brings:

• Open DSK and DMK files by just double-clicking over them
• Choose whether to detect file formats automatically or manually
• Choose whether to show or hide system and invisible files
• Sort files by name, extension, size, date and attributes
• Export multiple selected files at once
• See disk properties including name, date, DOS version etc.
• Navigate through disk sectors

October 5, 2009 – External Model III Drives for Pickup or Shipping Cost

The drives have been claimed. Thanks.

A site visitor has four external floppy drives with power supplies for the TRS-80 Model III. He is not sure if they work, but advised advised that they are from a working system that was retired two decades ago.

He has popped the cover off of one of them and confirmed no unusual corrosion, and the belt appears to be in decent shape. The ribbon cables are also with the drives, and the set includes a matching, under-desk bay that can hold two of the drives.

He is willing to give them away as long as he is not out-of-pocket. If you want to pick them up (Prior Lake, MN) that’s fine, and if you want to pay pack/shipping, that’s fine.

Email me if interested – first come first served.

November 6, 2009 – XTRS Updated to v4.9d

Although it happened in July, I just found out that Tim Mann’s TRS-80 Emulator in Unix, XTRS, was updated to v4.9. The updated version can be downloaded from Tim Mann’s XTRS web page [Link Deleted] or from the emulator web page.

November 6, 2009 – SDLTRS – New TRS-80 Emulator for PC/MAC

Mark Grebe has ported Tim Mann’s XTRS emulator for Macintosh OSX, Windows, and Linux. While it is always good to have a new emulator on the scene, this is big news for those MAC users out there, as there has not been a workable TRS-80 emulator for the MAC in many years.

As many know, Tim Mann’s XTRS offers Model 1, 3, and 4/4P emulation, with cassette, 5″, 8″ and hard drive emulation. It emualtes sound, mouse, joystick, and printer, and can do data I/O between the emulator and the host operating system.

SDLTRS expands on this and adds:

• Windows and Mac OS X support.
• Fullscreen display.
• Text based GUI on Windows and Linux, and in Fullscreen mode on the Macintosh.
• Configuration files.
• Disk LED Indicators on screen.
• Creation of Disk images inside of the program.
• Saving and loading of disk sets.
• Saving and loading of emulator state.
• Copy and Paste of text to/from host and emulator.
• USB Joystick support.

The MAC version also adds:

• Graphical interface, include Media management with graphical representation of the disk drives and cassette.
• Printer emulation of Epson FX-80 and CGP-115 Plotter/Printer, with output to PDF files.
• Debugger in seperate program window.

SDLTRS can be downloaded via the SDLTRS Web Page [Link Deleted] or from the emulator web page.

November 11, 2009 – Various Site Updates

A page with TRSDOS 1.2 patches has been added, the page of the TRSDOS 1.3 patches has been GREATLY expanded, and Miguel Dutra’s VDISK utility has been added to the Virtual Disk Utilities page.

December 3, 2009 – New DSK/DMK Tool from Matthew Reed
