Overview of This Site

This site is devoted to providing extensive information on the line of TRS-80 personal home computers, with a specific focus on the Model I, Model III, and Model 4. There is also SOME information on the Model 100/102, Model 200, Model 600, Color Computer, and Pocket Computer lines as well as Printers. Information from these links includes product descriptions, catalog numbers, pictures, prices, operations, hardware, software, etc.

You can also find utilities and information on how to read TRS-80 disks and how to read TRS-80 tapes on a modern PC, how to run them on a modern PC using a TRS-80 emulator, and utilities to manipulate the disk images and cassette images once you have them converted. I can even read your disks for you into a format which you can use in a TRS-80 emulator on your PC.

Other information on the site includes online reference manuals for Level II BASIC and NEWDOS/80, as well as information (and walk-throughs) for the Scott Adam’s adventures and tips/tricks/zaps/easter eggs. There are even utilities to play your old ORCH 80/85/90 files again!

There are pages devoted to TRS-80 DOS’s such as NEWDOS/80, DOSPLUS, MULTIDOS, and CP/M, as well as to Hacks for TRS-80 hardware, for Hardware Repair, and for Modern-Day Hardware which can substitute for TRS-80 Hardware.

Almost all of the magazine covers featured on this site also come with details about the issue, and the table of contents of the articles which were present. There are currently 200 pages to the site (not including news postings), so feel free to poke around.

You can even search through the TRS-80 Software Archive, the TRS-80 Magazine Tables of Contents, and the TRS-80 Catalogs.

Do you have real TRS-80 disks just lying around? LET ME RESCUE THEM

While TRS-80 disks were not made to hold data for 35 years, the data is most likely still there if the disks were stored properly. However, that is a big “if”.

If you have TRS-80 Model I, III or 4 disks lying around, please contact me. I can read those diskettes into a format which can then be used on modern PC’s running emulators (letting you re-live your memories). This will also preserve your collection!

I do NOT charge for this and put together this FAQ for those interested.

  6. I have a model 100 in vinyl case. In great shape, with manuals, plug in, ac adaptor, and “portable disk drive.” At this point, have not attempted to boot….

    Any thots on starting it up after 35y? And I need to sell… and no idea how to price.
    thanks

  7. I have a TRS-80 model I, original monitor and cassette tape player; a disk drive, expansion board, some software, LDOS. Does anybody want it? I live in Houston, Texas. I’m hoping to get something for it, but probably if someone pays for shipping I’ll be happy.

  8. I have a TRS-80 Model II, monitor + Expansion Board + Floppy Drive: up and running. I have programs selfmade or bought, some of them working.
    I made a connector to replace monitor by a W10 computer and monitor. I use different camera solutions (e.g. normal VLC and OBS studio) so I can read better and record anything on the screen.
    Anybody interested in old SW exchange or ideas for new applications?
    What I need are button caps: “7” and “8” : or caps anything on it: they are broken and lost but the button itself is working.
    I also have a WATANABE WX4675 plotter controlled by TRS-80 but the X direction plastic driver chain broken. Any ideas to fix or replace?
    I would appreciate your help or advice.

  9. @LynnDavis Just saw your post. Are you still Interested possibly in selling? I’m very possibly interested in purchasing. Feel free to text or call me at +1 917 921 1039. My name is Michael. Hope to hear from you!
