TRS-80 Color Computer: Radio Shack's $399 Micro from 1980!

Wetenschap en technologie

A retrospective look back at the original TRS-80 Color Computer, 40 years later! Radio Shack sold the CoCo range of machines from 1980 to 1991, and although it never took the low-cost home microcomputer market by storm, it's still an 8-bit system worth revisiting and enjoying today.

    Being a musician, you'll get this. How crazy is it that most of the Korg Volca series STILL uses audio like the cassette drive to transfer data. I'm specifically talking about the Volca Sample here, original. (The one I bought, and love) LOL eh? .. THEN they got smart and made the Mark 2 with USB .. considering selling this one and buying that one. But then, I'm running the Pajen custom firmware, and IDT the Mark 2 has all the functions Pajen put in there. Or perhaps he's done a custom firmware for the Mk 2 now. I haven't checked. hmmmm

    I had TRS-80 COCO, the silver beast. I bought an upgrade module that increased ram to 16K (or maybe 32?) and included extended basic. The joysticks were very useful for plotting graphics. I would use two joysticks and draw a line between the two (hv) positions on screen. Flipping through the 6 pages of graphics memory while drawing made for some interesting psychadelic affects. Oh, I recall also being able to poke an address which greatly increased the computer speed. The music in games was sped up so it didn't sound that great but it was neat to be able to run code faster. Oh how I wish I knew what happened to that system. I had so many early prototypes of my games including home made fonts, stock market simulator, gravity and planets, etc. Thankfully Rasbperry Pi and Python have let me continue to explore my ideas.

    Yes, the sound on the tape sounds exactly like a MODEM. The usual way the data was encoded for tape storage was precisely the same way it was encoded for MODEM transfer, and this was the method used right back to the MITS Altair 8800. (Commodore didn't use this method, they had a true digital format, and the same one on all their 8-bit machines.)

  • David Evens
    David Evens12 dagen geleden

    It got the "TRS-80" moniker purely for marketing recognition of the Model I and Model II. The CoCo ran on the Motorola 6809 processor (and was pretty much the reference design from Motorola, as was the Dragon 32 and Dragon 64 from Wales, with both easily converted to run software for the other) instead of the Z-80 that was the original source of the "80" in TRS-80. Oh, and the way Dragon Computing collapsed resulted in new old stock Dragon micros only running out a few years ago. (You used to be able to buy them from a big retro hardware website in the US, which also had an impressive array of old floppy disk mechanisms for sale. Too bad a working 8 inch mechanism cost at least a grand five years ago. I really would like to get hold of the full schematics and plans for one to see if they could be replicated by some modern fabrication company.)

    I had a CoCo back in the day. I found that there was an unused address channel on the memory controller. If I soldered additional RAM chips ontop of the existing ones, with the address leg bent outwards, and ran that to the unused address channel, I could create a second address space! Using a physical switch, I could physically switch between the ram! So, I could hold programs in memory, switch to the other memory address and run another program there! Kind of like a virtual machine! So one could be running a BBS program and the other could be doing word processing or something else! I then found that there was a guy named William Gates in Texas that was selling a CPM style OS. I purchased a copy, and a friend had an eprom burner. I replaced the coco eprom with my custom eprom and now my coco had an amazing amount of capabilites...including lowercase decenders! Yay!

At least I had a floppy drive while most of my friends had tape One odd thing was, my TRS-80 didn't have a "QWERTY" keyboard. In high school, I couldn't practice my typing at home.

I actually used this computer and wrote a bio rhythm program that I ended up selling ( folks their bio rhythm ) by placing a ad in the “national Inquirer” I still have one of the games I wrote it’s print out is downstairs in my studio it was called tunnel run teaching myself to write extended basic from the book, I feel was one of my biggest accomplishments that I ever did by myself...😹😹😹

    My first computer (not counting the Pocket Computer 1) was the CoCo: 16k of Ram that I upgraded myself to 64k. Later, I added a floppy drive, when it was going for 1/2 price. For a monitor, I used a TRS-80 Model 1 monitor a friend sold me. I used that CoCo for many years, even after I bought my first PC-compatible: the Tandy 1000. By then, I also owned a PC 2 and a Tandy 100. Today (Jan 2021) I still have that old CoCo and it still works -- even most of the disks.

    The "not quite color" technique used to print the manual was called duotone and I loved setting those up. Er, not those specifically but ones like it. Back when full color printing was super expensive, duotones let clients add a splash of color on every page for a relatively small increase in cost.

    My first computer was a CoCo1 with a 64k upgrade and eventually a 32k CoCo2. I loved those stock joysticks for many of the games that actually made use of the analog potentiometers to control the speed of the player’s character. It’s especially appreciated on the game Doubleback; which I missed so much that I bought a CoCo2 and another CoCo1 to play it again 30 years later. Dungeons of Daggorath is amazing and even warranted an entire quest in the book, Ready Player One. Audio Spectrum Analyzer also appeared in the concert scene in the classic movie Revenge of the Nerds. Take THAT, Apple!! I still enjoy programming my CoCos in BASIC and using the cassette tape for storage but I also have a floppy disk drive, Multipak Interface and a few other upgrades that I couldn’t justify spending money on in the 80’s. I never got into the alternate operating systems or the SD adapter, though I’ve considered it to simplify downloading and playing software from the Internet. I’ve had some success just using CoCoTape on my PC and sending the cassette audio through the headphone port, through a cassette cable to the CoCo; preserving some of the tape loading experience.
