February 3, 2013 – Lance Wolstrup Passed Away

I am sad to report that Lance Wolstrup, publisher of TRSTimes, passed away on Jan. 2nd at 70. He was an avid TRS-80 collector and a supporter of the site. He will be missed.


February 4, 2013 – School Looking for Model 3, 4, or 16

A district school in S. Carolina is looking for a Model 3, 4, or 16. They can afford to pay shipping but nothing else. If anyone has a Model 3, 4, or 16 that they were looking to dispose of should the right cause arise, perhaps this is it. If you are such a person, please contact me and I will put you in touch with the school. Thank you.


February 5, 2013 – Software Sourcebook Download

I was reminded that I had received permission to permit downloads of Software Sourcebook, 1st Ed. from Alan J Lewis who published the book in 1984.

February 20, 2013 – Added Software Manual Covers

While I continue to scan Lance’s immense collection, I have (finally) created a pages for the (covers of the) software manuals which have been archived to date. Of course, their quality swings WILDLY so if you have any manuals, please let me know!!! As always, if you have a friend in congress and would like to explain to them how it is INSANE that these are still covered by copyright, please feel free to give him/her a call; but until that is fixed, there are no downloads available. Links are on the right navbar.

March 18, 2013 – Model I Power Supply Replacement Schematics

I receive a fair share of emails from people with Model I Power Supply issues. While common wisdom is to cut open those supplies and replace the fuse, sometimes that is not possible, that is not the problem, or the individual is missing a supply altogether. I had asked Ian Mavric to look into the matter and Ian has now advised that Dean Bear has designed a replacement power supply for the Model I. It has enough power to drive both the Model I and the Expansion Interface, so two will not be needed. The graphic to the left are designs for a 120V and a 240V, depending on your need. Of course, I have not tested these, and have no idea if they work (Dean has been running his for over a year and Ian and Dean will be testing these schematics shortly), so build/use at your own risk.


March 23, 2013 – Model I Power Supply and Composite Video Cable

The emails about people needing power supplies keep coming. I have been working with Dean Bear, Ian Mavric, and David Cooper to put together a power supply page, featuring technical information, repair instructions, and the below schematics with a hotlinked parts list. I have not made the page public as we want to prototype and test the thing first, which is expected to start this weekend. Stay tuned.

Another popular request is for a TRS-80 to Composite video cable. Ian Mavric has finally cracked that, and hopes to make a video on how to construct such shortly. Again, stay tuned.


March 24, 2013 – Model I Power Supply

… and thank goodness for testing. The schematic has been replaced. If you were starting with the prior schematic, consider yourself warned … The DC was being over-powered by the 7.5V transformer and the schematic has been revised down to 6V, which after the bridge gives an output around 16.7VDC. With the 7.5V transformer we were getting 23.6VDC which is at the upper end of the spectrum (if you go by the Sams computerfacts book) or wildly overdriven compared to what is marked on the stock TRS-80 transformer.

We will continue to test before making the web page public.


March 25, 2013 – Building a Composite Cable for a Model I

Ian Mavric has created a YouTube video on how to build a composite cable for a TRS-80 Model I.

It can be found on the Model I Composite Video Cable page.

April 16, 2013 – Still Going

I continue to scan magazines which were already present but which were in HORRIFIC shape (scanned as B&W, a cardinal sin, with uneven page sizes etc) so none of those are showing up as news. As part of these rescans, however, I am revamping the magazine/manuals/books to be a little more consistent in terms of layout and size. For the magazines, where they used to link to a non-wordpress page with a vague representation of frames to bring you back, the sub pages are now smaller consistent pop-ups.


April 17, 2013 – TRS-80 Emulator for Android

TRS-80 Emulator for Android

Arno Puder has advised that he has released v1.0 of his TRS-80 emulator for Android.

According to the Google Play store description:

This is the first version of a TRS-80 emulator. It is a port of xtrs to Android. Please note that this version is alpha-ware. At the moment you can only run Model 3 programs in text mode. More features are to follow as I find time. I’m releasing my work under the Apache V2 Open Source license. Instead of giving this app a one-star rating either wait or head over to SourceForge, create a patch and send it to me! If you have some graphic skills, perhaps you can help with by contributing a nice app icon. You can find the complete source code at: https://github.com/apuder/TRS-80.

Google Play link is https://play.google.com/store/apps/details?id=org.puder.trs80.

April 25, 2013 – Hard Drive Emulator for a Real TRS-80 Model III/4

Ian Mavric will be handling sales and distribution of Hard Drive Emulators for the Model III. The circuit boards will be attached to a TRS-80 just as TRS-80 hard drive would, so the TRS-80 will believe a full fledged hard drive is attached; but the media itself will simply be a SD card.

Ian intends to offer the product in three different forms:

  • Kit A – just the bare PCB and a CD of dropbox data and is best suited to hard-core electronics enthusiasts who have the equipment to program GAL and PIC chips. All parts need to be supplied by the builder, and a complete BOM list is provided.
  • Kit B – the PCB, and programmed GAL and PIC, and a CD dropbox of data suit people capable of soldering together a project kit of some complexity. All parts apart from the GAL and PIC need to be supplied by the builder, and a complete BOM is provided.
  • Kit C – fully assembled kit, tested, partitioned and loaded with DOS ready to plug into your Model III, 4, 4D or 4P. Boot floppy disk provided. Just connect it to a 5V power source, a hard drive cable, and boot the floppy.

Prices have yet to be confirmed and Ian will know more when he starts building them. Each is hand made and then tested on Ian’s own TRS-80 system with the OS installed to make for easy set up.

The initial hard disk image supplied on the drive will be 42Mb divided into 6 partitions and installed OS will be LDOS 5.3.1 for Model III users and LS-DOS 6.3.1 for Model 4/4P/4D users.

To be put on the waiting list, contact Ian at ianm at trs-80 dot com.

May 8, 2013 – Video Comparing TRS-80 Hard Drive and TRS-80 Hard Drive Emulator

As you may know from prior news items, Ian Mavric will soon be selling a TRS-80 Hard Drive Emulator; a tiny circuit board with a standard SD card that plugs into an actual TRS-80 Model III/4/4P via its standard 50-Pin Bus and then acts exactly as a TRS-80 Hard Drive would act. Ian has prepared a video which demonstrates his TRS-80 Hard Drive Emulator. The video starts off showing booting and using Model 4 with an actual TRS-80 Hard Drive attached, moves on to show the insides of a TRS-80 Hard Drive system, and then shows the same operations (albeit on a Model 4P) using his emulator. If you are interested in purchasing a TRS-80 Hard Drive emulator, contact Ian Mavric at ianm at trs-80 dot com.

May 14, 2013 – Z80ASM Updated to v1.2

Matthew Reed has released v1.2 of his PC-Based Z80 Assembler, updated to fix a small bug. Z80Asm assembles TRS-80 assembly language programs and creates /CMD files that will run on a real or emulated TRS-80, but it runs on the command line of your Windows PC.

More information can be found on the official Z80Asm Page. The file can be downloaded here


May 16, 2013 – CoCo/Dragon Emulator

Joe Hagen has let me know that a new CoCo/Dragon emulator, called XROAR, has been released. XRoar is a Dragon emulator for Linux, Unix, Mac OS X, GP32, Nintendo DS and Windows. Due to hardware similarities, XRoar also emulates the Tandy Colour Computer (CoCo) models 1 & 2. The main XROAR page can be found at http://www.6809.org.uk/dragon/xroar.shtml.


June 1, 2013 – New TRS8Bit Newsletter

June 3, 2013 – TRS-80 Hard Drive Emulator Update

Ian Mavric has announced that there are now cases available for the freHD TRS-80 Hard Drive emulator.

For those who want to make their own freHD, Fred Vecoven has updated his site with tech details and information for electronics enthusiasts who wish to make their own FreHD from scratch.

For those who would like to at least have a pre-fab circuit board, The freHD pricing is $20 for Kit A (bare PCB and a CD of dropbox data), $50 for Kit B (PCB, and programmed GAL and PIC, SD card socket, battery holder, and a CD dropbox of data), and $250 for Kit C. A hard drive cable ($45) may be needed, or if buyers already have a TRS-80 hard drive they can use that cable with FreHD. More pricing information can be found on Ian Mavric’s freHD page.


  • freHD in action (Malcolm McLeod’s system)

  • freHD in a TRS-80-like enclosure

  • freHD in a clear enclosure

Ian also has made a new video with an explanation of what you get when you buy the freHD and how to hook it up and get started.


June 13, 2013 – Shrink

I note that a few pages are so large that WordPress chokes on them which is, in no small part, because the site is so expansive that the HTML is pushing the limits of what WordPress can serve. I am trying to shrink large pages through use of CSS and am currently working on the NEWDOS/80 zap page (the largest file that looked like it could transition to CSS; In revising just the first 11 zaps on that page, the HTML shrunk 3K). I think the organization of the site, other than the Zaps/Mods pages, seems to be fine; but the Zaps/Mods pages are unwieldy and not terribly useful. Any ideas how to better serve up the zaps/mods are appreciated as those pages are particularly large.


June 25, 2013 – TRS-80 Hard Drive Emulator Update

Ian Mavric has provided three documents to go along with the freHD TRS-80 Hard Drive emulator.

General, and ordering, information can be found on Ian Mavric’s freHD page.


June 30, 2013 – French Model I – Free for Local Pickup Only (Paris, France)

A complete TRS-80 Model I including the expansion, a DW II printer, all the documentation, even the original desk with 4 floppies, french keyboard, word processor with french accents etc. is available free for local pickup in Paris, France.

Owner says it was all stored away dry and clean on the attic, but has not been used in some time.

If you are able to pick it up in Paris, France, please contact me.


July 1, 2013 – New Repair Person in France

Update: Pascal no longer permits downloading if his schematics.

Pascal Holdry has advised that he can repair TRS-80 Model III’s and Model 4’s for those in need, making him the only entry we have on the TRS-80 Repairs page in Europe. For thse in need, Pascal’s information is on the TRS-80 Repairs page.


July 15, 2013 – TRS-80 Hard Drive Emulator Update

Ian Mavric has advised that the FreHD now works with the auto-boot feature of the Model 4P, which is being offered for no extra cost to FreHD buyers who own 4P’s.


July 20, 2013 – TRS-80 Model I Hard Disk Adapter Board

TRS-80 Model I’s require an adapter board to adapt the 40-pin connector on the Model I Expansion Interface to a 50-pin connector for hard drives.

Since these boards are virtually impossible to find today, Ian Mavric has created an adapter board, so those with Model I’s can connect to a real TRS-80 hard drive or a FreHD SD-Card Hard Drive emulator.

The cost for the fully-assembled board (including Model I hard disk drivers) is $50.00 + Shipping. For those without the Hard Drive cable, cables are also available for purchase for $40.

The ideal system is a 48K Model I Disk system (in good condition) running LDOS v5.3.1 with a TRS-80 Hard Drive or FreHD.

As from this moment on, this adapter is now compatible with FreHD.


August 5, 2013 – Updates to Matthew Reed’s DMK Utilities

Matthew Reed, author of the amazing TRS32 emulator, has updated his DMK and DSK Management Tools: TRSREAD / TRSWRITE (Command Line) to v4.34 and TRSTOOLS (GUI) to v1.10.

Changes:

  • TRSTools wasn’t recognizing some TRSDOS 1.3 disks that it created itself.
  • The LS-DOS date patches that TRSTools applies were updated to fix a problem with the DIR command.
  • RSTools wasn’t recognizing certain LDOS/LS-DOS disks that did require the 2012 date patches.

August 18, 2013 – TRS-80 Hard Drive Emulator Update

Ian Mavric has gotten FreHD working on the Model I and is currently available.

It has been tested on the early and late Expansion Interfaces, early and late Model I ROMs, also tested on the LNW system expansion, and works with the Tandy and Percom-type doublers. It supports usual Model I upgrades like lowercase characters and double-sided disk drives.

To use it you need a Model I with 48K, a disk drive, and one of Ian’s Model I HD adapters, the interconnect cable, and the FreHD.

Speed and versatility are much better than traditional TRS-80 MFM hard drives, an the cost is less than a typical eBay Model I hard disk system.


August 20, 2013 – TRS32 Updated to v1.28

Matthew Reed has updated his TRS32 emulator to v1.28.

Changes Include:

  • The registered version can read/write images used by the FreHD hard drive emulator.
  • Epson FX-80 condensed state now persists after a form feed.
  • An error sometimes encountered when write-protecting hard drives is now fixed.
  • Behavior is consistent when selecting a hard disk file that has already been selected.

The emulator can be downloaded here and can be registered here.


August 22, 2013 – Modern PC In a TRS-80 Case

Mike Ford has taken a non-working Model 4 and, keeping the keyboard and case, transformed it into a system running an i5 3.1Ghz Motherboard, with two 4TB hard drives and Windows 8. Every step is documented, in detail, with pictures. It is great read.

You can read about it on Mike’s site at http://mechanicalarcade.com/TRS-80-Conversion.htm.


August 26, 2013 – TRSTools Updated to v1.11

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 v1.11; correcting a small bug.

You can download v1.11 here or visit Matthew’s TRSTools Page.

George Geczy, author of Supreme Ruler, Millionaire, Exterminate, and Battle of Zeighty, has graciously allowed his software to be posted. Links to Supreme Ruler are live, and links to the rest will hopefully go up tonight.

In honor of the 30th anniversary of Supreme Ruler, his company, BattleGoat Studios, is developing a a PC and MAC version of the game. For those interested, the project description and kickstarter link are:

BattleGoat Studios is delighted to announce the launch of their Kickstarter to fund the final stage of development on their upcoming Strategy game, Supreme Ruler 1936 for PC and Mac. For TRS-80 enthusiasts, this is the current version that all began with Supreme Ruler for the TRS-80 in 1982 (back then the company name was JMG Software International). In fact a picture of the game running on a Model 4P is featured on the Kickstarter page!

October 28, 2013 – Project to Use a Raspberry Pi to Read TRS-80 Disks

Alan Page is working on a project to use the Raspberry Pi to read TRS-80 floppy disks. As of this time, I believe that Mr. Page is able to read unprotected single-density disks, with future updates to include writing, double-density, and protected disk actions.

You can read about his project at virtualfloppy.blogspot.com.


November 7, 2013 – FreHD to System-80 Adapter

The FreHD seems to be a project in full swing. Andrew Quinn and Ray Whitehurst have developed an add-on adapter which will allow the FreHD to work on a SYSTEM-80 with NewDos/80 v2.5 and LDOS v5.3.1. The adapter would plug into the P2 socket (or 50 pin header) on a System-80. The board is currently in prototype.
