They say you can't judge a book by its cover. That definitely applies to this TRS-80. Thank to Tim Lindner for donating this machine to me. @timlindner

This is a computer that I built when I was 21 or 22. Used to manage RS stores in the early ‘80s. Please forgive my hackery.

Yeah, as a member of the Coco community, I know of, as well as know Tim Linder. Very cool guy who's one of the biggest contributors to the CoCo community. Very cool guy!

Oh man, I love custom builds like this!! Can't wait to see this resurrected.

When I worked at Motorola I worked on the development of the Color Computer for Tandy. I have an old Color Computer in my attic that I have not looked at since I put it in the attic in 1992. When it first came out I worked with a co-worker and we sold an eprom programmer and a static ram board that plugged into the game port. I have been thinking of digging it out just to play with it but I currently don't have space to set it up. Watching your video brought back some old memories of the fun I had working on that project.

The fact that the tuner was tossed in to make the TV work just kills me. I mean, it probably works great but... just... wow. I'll just imagine that they're massive picture adjustment pots instead.

@gregorystrohmeyer3023 Год назад

I remember when these machines were brand new and I wanted one so bad in the late 70s through the 80s but couldn't afford one. It breaks my heart to see these machines, that I once dreamed of owning, being neglected and filthy dirty. That is probably why I enjoy watching you and others restore these pieces of history.

@raggededge82 Год назад

What a unique piece of history! I can't wait to see it restored to it's original wacky glory.

@zero0ryn Год назад

I did something similar with an Amiga 500, putting it into a case for some CP/M machine with was very flat and deep and featured 2 floppy drives on the front. it worked very well and was the perfect size for the A500 main board. pity I never took any pictures of it.

@wintermute740 Год назад

I did a CoCo3 repack in a full AT tower back in the day, but this repack is just... brilliant... Aside from the sketchy gauges of wires used and the fact that it appears that very few of the components were actually mounted.

This is a master class on why you ALWAYS investigate something before plugging it in to test it. Well done sir!

One of my childhood friends Dad's worked for Tandy and the TRS-80 "Trash 80" was my first hands-on keyboard exposure to PC's. We were in the FW area. He then gave me an Adam Computer and I don't remember the specs but I hooked it up to our vacuum tube cabinet TV and it had two cassette drives. My first and only ever store-bought system was the Tandy 1000SX in '86 for about $3,500. I built a 8086 clone the same year with another elementary school friend. I've been in IT since. It's awesome to watch your vid's that help to preserve our tech history.

Used trs in early to mid 80’s and eventually bought what they called a transportable. Prior to laptops, it was early one portable enough to carry on a plane. The keyboard was the lid on its end cover a 9” mono screen and the disc drives. No harddrive, just two 128k floppies. Boot drive and data drive. Even had to take an incomplete for a paper in grad school, because the floppy became corrupted. Had to retype the whole 50 page project to graduate. Lol. I never forgot about backing up files after that. Loved the video.

@marvinlevine511 Год назад

My first computer was a TRS 80 with a cassette tape drive. I eventually added a floppy drive. They were singled sided. I would cut out the other side and was able to flip it over and double the capacity. Brings back a lot of memories.

What a time to be alive - to find these archeological artifacts our ancestors built, see them come back to life, and that we’re all crazy enough to see it restored

@cliff481 Год назад

I still have my original trash 80 which I bought in 1980 or so. It was 4K when I bought it and I remember buying an upgrade (memory chips that we soldered in parallel over the existing chips) and a plastic glue on 16k emblem (?) to replace the 4k one. Cassette load and save (CLOAD CSAVE) before hard drives were cheap enough for the general public, and "special" cassettes that in the audio trade we called leaderless. Later I bought a machine code converter module. What a difference that made. Still have them and the player recorder too. Thanks for the trip down memory lane.

This reminds me of those "barn find, will she run" car videos that I like to watch. Kinda fun to see you work on someone's vintage computer "rat rod." Yo, Adrian.. will she run?

@gen-amb Год назад

In 1980 I got a job at a Radio Shack and worked overtime to be able to afford a TRS-80 model I with 4K of RAM and Level I BASIC. Over the years I added 16K RAM and LEVEL II BASIC ROM (and upper lower case letters) upgrade, a krazy-glued piece of green plexiglas to the RCA, an expansion interface, eventually 5 1/4” disk drives, an Omikron CP/M adapter to dual boot into CP/M, and ultimately started using BBSes through a 110 baud modem, and finally an Epson MX-80 printer. Digitized my first audio through the cassette interface using a machine code program I keyed in hex from an 80 MICRO magazine. Learned a lot from it.

@phoenixgaming746 Год назад

What a Classic Vintage TRs-80 computer shame some working parts were missing Adrian when you open it up

@joelavcoco Год назад

Another commenter suggests that this may actually be the Extended Color BASIC ROM. If this has an Extended BASIC ROM, but not the Color BASIC ROM, it could be that at one point the original ROM was swapped out for a custom EPROM that booted directly into OS-9. OS-9 wasn't quite as useful on the CoCo 1 & 2 due to the limited memory, but it was definitely a thing.
