CLAIMED – CoCo I Free for Local Pickup in Frederick Maryland

Update: Claimed
A site visitor is giving away his original Radio Shack Color Computer with a few accessories, free for local pickup in Frederick Maryland. He says:

The Color Computer boxes are in ratty condition – that is they look to have gotten wet either before, or after, the rats and squirrels started chewing. The good news is I must have been very thoughtful when I put every thing back in the original packaging since the equipment all looks good to me (see pictures).
Here are pictures showing (and including some idea of the packaging as everything goes into its own box):
– back of the Color Computer with serial number (possibly meaningful in determining when it was manufactured)
– front of the Color Computer
– Color Computer Disk Drive with all the parts
– Color Computer Multi-Pak Interface
– Color Computer Graphics Tablet (X-Pad) – notice the condition of the box – yet the Tablet is totally clean
– Color Computer Dot Matrix Printer (DMP-100)

Site Updates

I don’t usually post site updates, I just make them. I know I should be keeping better tabs on it 🙁

Anyway, here are a bunch of site updates that have occurred over the past however long:

  • The ROMS page has a breakdown of what changed from v1.2 to v1.3 of the Model I ROM.
  • I continue to scour old magazines for ads for software which was advertised, and adding them as “MISSING” to the archive.
  • Every result from the search page should have a screenshot (or a note that none was available, no printer output, etc)
  • Since people, apparently, LOVED to remove author credits from these programs (or putting their own names on them), I am using those screenshots to determine whether “Author Unknown” programs are actually known.
  • Every time someone emails me a hardware question (which I send to Ian Mavric, thanks Ian), I update the repairs page with their question and his answer.
  • I keep adding boxes to help fine tune archive searches. This is mainly because the search page is how I find things too, so if I am trying to find all software without a screenshot, for example, I can do that.
  • As people point out pages which do not render correctly (because they are pre-HTML5), I fix them.
  • Added a /SYS guide for TRSDOS v1.3 on the DOS Tips and Tricks page.
  • Caught up on all the unsorted images and put solid effort into figuring out if they were good files or bad files, or needed 3rd party software.
  • Fixed the bug that was keeping the ads from coming up on the archive searches, at least for me. It seemed anything being served from a directory called /ads/, or had a filename called ad-xxxxx, got blocked!

New TRS-80 Trash Talk Podcast

The podcast TRS-80 Trash Talk # 32 is out now.

In this episode they start by previewing the upcoming Tandy Assembly 2019. They have a lot of big news to relate regarding the 3rd annual gathering of Tandy Radio Shack computing enthusiasts in Springfield, Ohio. They also discuss a new document archiving project of original Radio Shack Customer Service Bulletins. There’s the usual segments on new projects, new acquisitions, listener feedback and the book review. They then try to decide what do you do with a wall of Model I Video Displays. Finally, in their interview segment, Pete Cetinski talks to Tandy Radio Shack marketing executive Buzz Murphy. Buzz relates his experience at the company while riding the incredible wave that was created by the original TRS-80 microcomputer release in 1977.

Anyone have a CHROMATRS

UPDATE: The creator of the CHROMATRS has been working with Pascal.

Pascal Holdry is still working closely with the creator of the ChromaTRS reverse engineer the ChromaTRS, but there are still some questions about the circuit board that remain unanswered.

If anyone has a ChromaTRS would you please reach out. I think even just a high res photo of both sides of the board might do the trick in identifying some missing components.

Thanks.
