January 3, 2014 – IDE Hard Drive Interface

James Pearce has developed a simple DYI IDE adapter for the Model III/4. “The Lo-tech TRS-80 IDE Adapter rev.2 is an external IDE storage adapter for Tandy TRS-80 model III/4/4P PCs, enabling connection of standard IDE drives (and CompactFlash cards, with an adapter).

To keep his design down to just a few 7400 series IC’s, it ignores half the data coming in from the device so as to provide the 256-byte sectors the TRS-80 expects.

The web page describing the adapter is Here and the Wiki is here. The Wiki page lists the components, power needs, etc. and also provides the Eagle and Gerber Files.

Laurie Shields has ok’d her files to be downloaded. The links in the Software Archive are now live.


January 19, 2014 – Another Model I Power Supply Design

Charles has developed a Model I power supply using more readily accessible parts in the USA (i.e., common transformers available from Radio Shack). All steps and parts, including an external enclosure, are found in his PDF. Thanks Charles.


January 20, 2014 – Space Battle

Rick Papo has taken a look at the copies of his game, Space Battle, and has figured out that they suffer from issues based on some copy protection he had inserted in the code (to prevent saving another copy to tape) and that USR routines were different under disk basic. While the 1978 and 1979 versions of Space Battle remain posted, it is the 2014 version which Rick advises is the one to use.


january 22, 2014 – ORCH-90 Schematics

Update: Pascal no longer permits downloading of his schematics.

Pascal Holdry has deconstructed the very hard to find ORCH-90 board, and has prepared schematics and gerbers for those who wish to build their own.

Pascal’s site, which is in French, can be found at http://www.prof-80.fr/.


January 25, 2014 – Cavern Quest

Barry Diller has ok’d the posting of his game “Cavern Quest,” which is now live in the Software Archive. Barry wrote Cavern Quest in 1982 while in college. Thank you Barry!

February 21, 2014 – Any C Programmers Out There?

Update: George Phillips, author of the Model I/III/4 emulator TRS80GP has graciously offered to do the feature implementation. Thank you George!

If anyone out there is fairly proficient in old timey C, has some time on their hands, and thinks they can handle this project, please let me know. As many of you may know, Tim Mann has developed amazing software to use a Catweasel to read and write TRS-80 disks. As I have learned from reading tens of thousands of disks, not every disk has fared so well over the past 35 years, and it is quite disheartening to see the program undergo numerous retries of varying success on a given track, to wind up giving fewer good sectors than it had read on a previous retry, simply because the retry counter expired and THAT read wasn’t as good.

To this end, if anyone out there can assist in tweaking the existing CW2DMK code which Tim Mann has prepared so that each time a track is read, the good sectors are put into an array, and when the read is done, the track is written out from that array; ensuring that if a sector was read good even once, it will be there for the output, instead of being discarded by each successive track retry. It would be best to set this up as enabled by a command line trigger, so those who wish to read without the cache can do so.

Any volunteers?

With George Phillips having prepared a beta of a cached-best-track modification to CW2DMK, I find myself in need of test disks. For those visitors out there who have not yet sent in their disks for converting, now would be a great time 🙂 Please remember that the data on these disks isn’t getting any fresher!


March 17, 2014 – New DMK Utility by Alan Page

Alan Page has created a utility which will view and edit DMK images as well as allow for side-by-side sector and track comparison of two DMK’s. It works on single, double, and mixed density DMK’s. CRC’s are updated with changes. His downloads are non-functional so download it here.


March 22, 2014 – Catweasel Software Mods Progessing

Despite not even having a Catweasel card, George Phillips has made amazing strides with modifying Tim Mann’s Catweasel software to output the BEST track read instead of the LAST track read. He is toying with the idea of actually repairing bad sectors based on bytes which are read differently, bringing a far higher level of granularity than I would have hoped. Stay tuned, and thanks George!

May 6, 2014 – Another TRS-80 on TV

A new series on AMC called HALT AND CATCH FIRE is running a trailer/commercial that starts with a TRS-80.

Of course, a technical consultant might have been nice, as drive :0 is empty while :1 is populated, and those are MSDOS commands, not TRS-80 ones … but, hey … the Model III lives on !


May 19, 2014 – Catweasel Tools Updated to 4.5 (Unofficial)

George Phillips has completed his work on updating Tim Mann’s Catweasel Software. Although it is numbered v4.5, it should be considered “unofficial” in that it is up to Tim Mann as to whether he wishes to accept the changes or not. The meat of the changes are:

  • The ‘-j’ option which re-uses good sectors from previous track reads to replace bad sectors. The idea being that a successful read of a track can be obtained in the face of inconsistent failures. For example, you might read a track once and get sector 5 failing. Then sector 11 failing the next time. But my merging the two reads you’ll get the full track.
  • Additionally there’s ‘-y’ which is something David Cooper wrote to prompt for more retries when a track has used all of its retries up.
  • Ira wrote code to detect when the 2nd side of a diskette is in MS-DOS format and ignores it if it doesn’t match the format of the first side. This is for when trying to read a TRS-80 formatted single-side diskette that used a pre-formatted MS-DOS diskette.
  • Finally, there is a ‘-D’ which dumps the raw track reads to individual files. While primarily used for debugging purposes, it also could be of interest in terms of preserving data more precisely and archiving bad data in the hopes that improved bit stream translation algorithms can recover it at some later date.

The ‘-j’ option has been fairly extensively and we’ve gone through a number of bug-fixing rounds to get it where it seems quite robust and reliable. And, most importantly, useful. There have been many cases where it manages to get the data off a diskette where many retries fail to get the perfect track.

The new version MS-DOS executable and source code are available Here.

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). One of the stories can be read at Extremetech.

December 16, 2014 – Phillip Ereaut Has Passed Away

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.
