Heh, nostaliga, it's not what it used to be 
My very first computer was a Tandy trs-80 coco1. I'd love to get one again some day (prefereably a coco3 though, one of the most under-rated 8bit machines ever in my opinion), but I unless I come across one particuarly cheap my amiga upgrades will come 1st.
The company I used to work for (Delmar Co) used to sell 68K based computers and owned a Marine electronics company and a Radio Shack franchise.
I alway like those computers too. Nice processor and while the graphic wasn't up to say Atari or Commodore it was mapped so that virtually any location in the processors memory map could be displayed via the VDG.
The problem with the Color Computer 3 was it was too little too late. Bean counters strike again. They limited the number of display colors (to keep it from competing with their PCs) and they insisted it cost no more to build then its predecessor.
Plus memory prices spiked and the 512K expansion card wound up costing more than the computer.
6809 assembly language was the last 8bit form of machine code I learned. It had some neat advantages over 6800 and 6502 code.
