The "CoCo 2" as it is affectionately called is the successor to the original Color Computer. There were actually three models - 26-3134B, 26-3136B, and 26-3127B which had 16K standard, 16K extended, and 64K extended respectively. The machine was essentially an evolution of the original.

Upgraded BASIC ROMs were also available to add a few minor features and correct some bugs. Also a redesigned 5 volt only disk controller was introduced with its own new Disk BASIC ROM (v1.1) adding the "DOS" command, which was used to boot the OS-9 operating system by Microware. (64K memory required)

I had upper and lowercase, i used a custom color basic rom, dont remember the name, but it had all the things Michael Evans missed, i rememebr that it had great sound, when i used a program called MUSICA it sounded MARVELOUS, it didnt sound like it was one channel only, dont know if it really was, also used OS9 and dynacalc, elite file, and other productivity tools and no other machine had things even close to those, I think i typed every code in the rainbow magazine into this things lol

I loved this thing. It was one of the best computers I ever had. I miss it. I had the 16k coco2, with the tape drive. I had downland,temple of rom, and dungeons of daggorath,and 3 text games on cassette called bedlam, pyramid 2000, and madness and the minotaur. Dungeons of Daggorath, is the first game I ever beat. I find it awesone, that Daggorath is one of the greatest vintage games.

Not-so-great graphics and sound. I had a TRS-80 Color Computer II. It wasn't the machine I had actually wanted. Over the years I discovered that this machine DOES have good software; you just have to dig a bit to find it. That and it has a 6809 -- giving it more processing power than the 6502-driven computers of the time. In short, I learned to appreciate this machine and still do.

The Coco was only disappointing for kids who wanted to play video games, which an Atari "computer" was of course very good for (but precious little else). If on the other hand, you wanted to do some serious computing activities like word processing, spreadsheet, programming or hardware interfacing, without paying a mint, the Coco was the superior machine. In 1983 my Coco 2 was capable of running a Unix-like operating system called OS9 level 1, which was a true multi-tasking, multi-user operating system for which excellent versions of C, Pascal, Basic (Basic09!) were available. It also had a superior word processor and very fast spell checker (with over 100,000 word dictionary) in its TSWord TSSpell package. The Dynacalc spreadsheet was a fully functional spreadsheet program equal in functions and flexibility to early spreadsheets for the PC. Comparing the Coco's OS, languages and productivity software to that of Ataris and Commodores is like comparing Sheaffer Pen to a crayon.

This was my first computer. I hated the stiff "melted keys", the badly drawn uppercase-only text, the horrible green background and the fact that you couldn't move the cursor where you wanted. I hated how everything stopped when you played a sound (one channel only with no effects), the lack of sprites and the puny 16kb RAM. Still, I spent many many hours programming this thing, making my own games in BASIC (which was really the only way to have a lot of games on this computer). The first time I saw a friend's Atari 800XL, I realized just how crappy my TRS-80 was. He had hundreds of arcade-quality games on disk while I had cheap home-made games on tape. It's strange, but I still have some nostalgic feeling for this piece of crap.
