A site visitor is asking if anyone knows the technique for using a Network I to load SYSTEM files onto the "client" machines. Normally, such was done by CLOAD, but there was a method to use SYSTEM for Machine Language. Anyone know? Thanks!

A site visitor has a Model I with printer, cassette, and expansion interface. Free to someone who will travel to the Minneapolis-St. Paul area to pick it up. Emails will be forwarded in the order they are received - ira at trs dash 80 dot com. Thanks.

Ian Mavric has put together an instructional video on how to install a Model III hi-res board on a Model 4.

A site visitor has pointed out a story by Earles McCaul outlining how he wrote the book TRS-80 Assembly Language Made Simple.

Earles had previosly authorized me to make the book available for download!

It seems that 'a hacker who goes by GP2000' has made the news by getting a Model 4P to display the opening sequence of Dr. Who, complete with sound. Congratulations GP2000, who shall remain anonymous (except that we all know who that is).

Phillip Ereaut passed away on December 6th at age 76. Phil lived in Australia and was one of the first people to provide utilities to fill needs of the TRS-80 emulation community. Back in 2006 Phil wrote a program to extract files from a DSK/DMK image which was useful when all other means failed. He also wrote the only utility to display what the PDRIVE settings of a DSK image were (now a fuction that TRSTools offers). Finally, he wrote a program to show the track data and allow for hex editing of DMK and DSK images. Phil was a great supporter of the TRS-80 emulation community, and he will be missed.

A site visitor just pointed me to Peter Bartlett's M.I.S.E. project. It is an add-on board for a TRS-80 Model I (with or without Expansion Interface) which provides:

• Direct booting from the inserted CompactFlash card
• 10/100 Ethernet (up 8 IP sockets)
• Real-time clock/calendar
• 800 x 600 SVGA Output
• Joystick Port for Atari 2600 Compatible Joysticks

A site visitor in Madison, Wisconsin has a Model 4P which worked when last powered on a few years ago either free for local pickup or shipped for the cost of pack and ship. As always, emails will be passed on in the order received.

Radio Shack has filed for Bankruptcy. Although Tandy / Radio-Shack had long ago sold off any interest they had in the TRS-80, it is still a sad day. I am sure all of us have fond Radio Shack memories, most likely sitting there messing around with their Model I display model. Farewell Radio Shack.

Pascal Holdry has completed mapping the Microlabs Grafix 4.2 High Res Card.

Update: Pascal no longer permits downloading of his schematics.

Pascal Holdry has been working on the difficult task of preserving TRS-80 hardware by mapping them out into schematics and parts lists. Right now he is in need of information on the physical board of the Grafix 5.1 Card. If anyone has such a board and is willing to provide information, pictures, etc. to Pascal, that would be great. Please contact me.

Bas Gialopsos has reached out to let me (and you) know that he is in South Wales and can handle the repair of all TRS-80 models. His information, should you need it, is on the TRS-80 Repair page.

Google has been whining that the site is not mobile friendly, so I have been looking for "Responsive" Wordpress themes that will work without incredible problems. The new one, called DW Minion, seems to do that, although it will need to be configured, which will be slow in the coming.

The old posts definitely look bad, but since there are about 622 of them, I don't intend to clean them all up.

Otherwise, I am still reading disks for people, sending DOS disks to people, sorting through thousands of disk images, etc. I hope to have another set of eBay auctions soon.

Ian Mavric's new High-Res Graphics board for the TRS-80 Model 4/4GA/4D will be on display at this weekend's Vintage Computer Festival East in New Jersey.

It will be at the exhibit entitled "The Customized TRS-80" and will be shown along with the FreHD Hard Drive Replacement and demo software.

David Cooper was mentioned in a nice article on Today about retro computing.

A short video showing off the TRS-80 display at VCF East has been posted. It discusses Ian Mavric's FreHD and Grafyx Card. Link is http://hackaday.com/2015/04/18/vcf-east-x-the-not-trashy-eighty/

Mike Gore has ported Miguel Dutra's TRS-80 Virtual Disk Kit v1.6 to Linux.

Update: Pascal no longer permits downloading of his schematics.

Pascal Holdry has completed development of the Banc 256K memory upgrade for the Model I. According to Pascal - this mod requires only a single cut to the Model I PCB.

Matthew Reed has updated TRSTools, a DSK/DMK Utility with the ability to show BASIC files de-tokenized, CMD files disassembled, graphic files as graphics, etc., to v1.13.

Changes include [1] Fixing a bug that caused invalid 40-track JV1 disk images to be created, [2] TRSTools can usually recognize multiple LDOS/LS-DOS partitions in FreHD hard drive images, and [3] Support for handling TRSDOS 2.3B disk images is improved.

Miguel Dutra's TRS-80 Virtual Disk Kit utility has been updated to v1.6. I do not have a changelog, but know that this version fixes a major bug identified earlier this week by Mike Gore.

For those of you who have not had a chance to see Jim McGinley's GDC presentations on TRS-80 games, both his 2012 and 2016 presentations are available online.

A long time TRS-80 related site, www.trs-80.nl, run by the Dutch TRS-80 Users Group has been updated.

The Dutch TRS-80 User Group was established on 1 October 1978 to support the new home computer from Tandy, the TRS-80. The User Group made a quick start and grew to over 4000 members. It published a bi-monthly newsletter, Remarks, which was the main source of information for many first-time computer users. The yearly User Day was the main event for buying hardware, software and exchanging knowledge. With the demise of the TRS-80 the User Group became accordingly smaller. The remaining members aim to preserve the TRS-80 and the knowledge of this retrocomputer.

To do so, the User Group today presents a new website and the complete archive of 108 newsletters, Remarks.

The site is in Dutch, but for those using Chrome, Google will offer to translate the pages as you move around the site.

George Phillips, who has made many many contributions to the TRS-80 and the attempts to keep it alive through emulation, was the site's 1,000,000th visitor, and was kind enough to take a screen grab. Thank you George, and to the 999,999 other visitors helping to keep the TRS-80 alive!.

A new book (cover) has been added to the archive: Invitation to Cobol for the TRS-80, written by Lawrence L McNitt and published by Petrocelli Books in 1983.

A new book (cover) has been added to the archive: Real-Time Control With the TRS-80, written by Russel Genet and published by Howard W Sams in 1982.

Dusty has released the June 2016 issue of the TRS8Bit newsletter on his trs-80.org.uk web site. You can find all of the issues on his download page.

Pascal Holdry has completed development of the buffered expansion interface cable for the Model I.

Chris Osborne, @FozzTexx, has been tweeting a lot lately about his TRS-80 Model II repairs and other adventures in restoration and use.

Not only did he restore the keyboard to new-like state (using supplies from the Dollar Tree) he was been busy porting a version of Kermit (file transfer protocol) that does proper hardware handshaking, and creating a Linux CP/M cross assembler in the process.

Pascal Holdry has completed development of the printer interface cable for the Model I.

A site visitor has advised the following is available either free for local pickup or for the cost of pack and ship. As always, first come first served. Details as follows:

I have both a working TRS-80 Model I w/expansion interface and a Model 4p. Unfortunately most of the daily use software disks no longer read. I also have a hard disk drive for the TRS-80 from Clone Computers that no longer boots up. In addition I have manuals in good condition for TRSDOS 6.0, Dosplus 3.5 & 4.0, Montezuma Micro CP/M,and a Model 4p service manual. There are original software disks, not used except for installation, that may or may not be readable. We are moving and I will give it all away to whomever is interested in paying the freight or picking it up, rather than tossing it. We are located near Chagrin Falls, OH.

It is with a heavy heart that I announce the passing of the Teac FD-55GFR drive which has been used to make people DOS disks and to read people's disks for them. It was a loyal worker, but was felled by a particularly gnarly set of disks I was reading for someone. Its duties will be taken over by a Mitsubishi drive that seems to be doing well on its first day on the job.

Pascal Holdry has completed development of the Percom Doubler II for the Model I.

Pete Cetinski has improved his TRS-Box so that it now works with a serial port.

TRS-Box is a Dropbox client for the TRS-80 Microcomputer. It allows you to navigate and copy files from and to your Dropbox from your TRS-80.

Trs-Box used to require a TRS-80 Model I with MISE or a TRS-80 Model III or 4 with M3SE, but Pete has gotten it to run on any floppy or hard disk enabled TRS-80 which has a RS-232 interface (although will need to buy a serial-IP adapter).

If you are on Twitter, follow TRS-80 Trash Talk for all Tweets TRS-80. These guys are firing on all cylinders, going all the way to 65535, if you know what I mean.

They also produce a podcast and just interviewed Scott Adams on August 25. At time of posting their latest podcast is from August 3rd but check regularly for their latest.

While not TRS-80 related, it seems the DMK format is catching on. A French developer has written a command line utility to take DMK images of MSX disks, and convert them into a format usable by a SuperCard Pro device (which I suspect is something MSX related). Source is included if you want to have a look. The page can be found at http://lhalter.free.fr/mgr/

Also, the 80 Microcomputing Magazines and the Model 100 from the below posts are STILL available for those able to do local pickup.

As most of you may know, the Catweasel card is not currently being manufactured or sold and some may be looking for an alternate way to read/write TRS-80 disks on a PC. I was recently (re-?)advised of the existence of the Super Card Pro, and although I have not tested or used one, it does look solid from the stuff online.

The SuperCard Pro is a flux level copier/imager/converter of almost all types of floppy disks to a SCP format; currently any type of disk that uses an index pulse before and after data (which includes the TRS-80). The software that comes with the HxC Floppy Drive Emulator (http://hxc2001.free.fr/floppy_drive_emulator/) has a function to convert from SCP format to DMK format (your mileage may vary).

While the catweasel is/was a PCI card, this card is driven either from a USB port or as a stand alone device! It is powered by the USB cable. The bios/cpu on the card can be reflashed (via USB) so that the card can be kept up to date. Drivers are currently available only for PC's.

The card currently costs $99.95 and if you look at the PCB carefully, you will see that the creator has quite the sense of humor.

A site visitor in the Alexandria, Virginia area is offering a Model I system free for local pickup.

Details (From the donator): Model I, Level II, 16K. I purchased in in 1980 at the Springfield Mall in PA. It was working when I boxed it up in 1985 and stored it in a bedroom. Now there is a problem. I'm able to enter and run a simple program, but the characters displayed on the screen aren't as expected. I suspect the monitor is fine, and maybe a contact in the computer is corroded. I'm including the computer, monitor, power supply, cassette recorder, original box, two Level II Basic Reference Manuals and some cassettes.

Note (From Ira): My hardware expert, Ian Mavric, believes from the pictures that it is more than likely that the cause of the problem is that one of the video RAM chips has failed.

• Model I, Level II, 16K Computer
• Monitor
• Power Supply
• Cassette recorder
• Original box
• Two Level II Basic Reference Manuals
• Some cassettes

As always, to keep away those would say "hey, would you ship" (when the above states local pickup only), please contact me at freetrs@trs-80.com if you can do a local pickup and I will relay in the order received.

There is going to be another TRS-80 Trash Talk Live show this Saturday, Dec 30th at 9pm EST. We will be chatting and streaming the show live on YouTube. We'll also have a Skype call going for active participants that want to show off their TRS-80s or give a demo.

Andy Silverman was kind enough to point out that the existing software for the SVD does not function under Windows 10. The workaround is to use the CYGWIN1.DLL as is currently packaged with CYGWIN. Download CYGWIN, install, and pull the file from Cygwin\bin.

TRS-80 Trash Talk # 23 is out. In this episode the Trash Talkers welcome vintage computing podcast pioneer David Greelish as a guest host. Pete, Ian and David discuss how Tandy reacted to the the introduction of the IBM Personal Computer in 1981. Tandy Radio Shack had all the advantages with its massive distribution network, its existing business focused Model II computer and with the forthcoming powerful Tandy 2000 computer. How the company attempted to compete with IBM and eventually failed is the main focus of the discussion.

PLAYCAS allows you to connect a TRS-80 cassette input to a PC soundcard so as to capture the software for use in an emulator or archiving. Knut Roll-Lund has recently updated it to v2.0 with the following notes:

• Old Play CAS unfortunately had a bug of type copy-paste. It could not load read-only cas files. Easy bugfix. This lead to me making a new vesion also changing the user interface a little and adding a feature. The save features was kind of hidden so adding a few buttons for this and removing my entries from the option menu.
• Save text saves the anaysis content and may be used to detokenize basic for example or recover the source code for edtasm stuff.
• Save wav saves the prepared wav based on your load (storing programs as wav is not efficient but might be convenient. This wav is kind of perfectly formed and better than anything from real cassette.
• LNW 1kHz (new feature in 2.0) whenever enabled modifies the wav to go at double speed. So any TRS-80 with zip kit etc. at double speed can now load cassette without dropping to regular speed.

Paul T Schreiber has some information that should be of interest to anyone with an interest in the TRS-80. Everything that says "I" below is Paul ... this is a cut and paste ..."

Some of you may be familiar with former Tandy R&D engineer Frank Durda IV who recently passed away.

Frank was a SW (and also a bit of HW) genius. Really. A more loyal Tandy employee/fanatic does not exist. And he kept EVERYTHING.

Frank left, most importantly, a wife and 4month old daughter, a daughter he never saw, or got to hold, as he was hospitalized during her birth and died, without regaining consciousness, soon after.

His wife Corrine now has the task to sort through Frank's "collection", which by my estimate, is over 300 file boxes of "stuff". The Tandy stuff appears to range from Model 2/3 up to the AST computers (4000SX). I even uncovered a box of VIS hand controllers [shudder].

Frank and his team wrote the BIOS/drivers for probably 100 things, as well as TRS-DOS/LDOS/XENIX and so on.

It's going to take MONTHS to get it all sorted (she lives about a 40min drive from me), today I just grabbed the first 12 boxes in the garage I could access (there was a 1964 Teletype machine in the way).

What I plan to go is sort as follows:

a) SW - floppies, SyQuest drives, 8mm tape. You name it, Frank has it.

b) HW - board add-in boards and full computers. I counted about 12 Tandy computers. There may be 50 more, I don't know. There are 100s (yes 100s) of add-in boards.

c) books/manuals - I spotted several HW Reference manuals, a FORTRAN binder, and a photocopied dBase III manual. About 70% are Tandy originals, 30% copies.

What is the goal? The goal is 2-fold:

1 - Preservation

2 - raise funds for Frank's wife & baby daughter

Now, as we all are aware, this stuff is HEAVY. I'm in Texas, and have Fed-Ex, UPS, and USPS options. In some cases, I will put individual items/small lots on eBay, but for the most part, this stuff will be sold by weight. Like $15/pound or some such. I some cases I will be specific, other cases might me a "treasure chest of Tandy Wonder".

Now, I was 100% a HW designer at Tandy, but I have a few ex-R&D folks in my network I can see if they remember this stuff. If you are collecting 'rare' Tandy items, the 2nd box I looked in had 2 internal R&D use boards that were the audio and video portions of the Tandy Sensation! PC. Only 3 sets were made (2 for Tandy and 1 for MicroSoft) and Frank has a Tandy set (I even forgot I designed them!). These were used to write the drivers before the 'real hardware' was developed, and they were also used for the VIS development.

I hope to have 'a new batch of stuff' every 2-3 weeks. Mainly, I want this stuff to find "good homes", not to be flipped. I want to be able to have a decent amount of $$$ for his family.

Lastly: Frank ran a few ISPs as well. I'm not an 'IT Guy' by a LONG shot. But he has 10-20 Cisco doo-dads as well (1U rack routers, etc). I'll post a few photos for giggles, and next week hope to have the first batch for sale.
