Thanks for your reply and also for sharing your interesting first-hand account with us!

As you've stated the CoCo3 was indeed a much more powerful beast than the machine it replaced (Z80-based CoCo2, of which I owned a clone) and put it inline with the Tandy 1000 and it's 8088 CPU, which in terms of basic performance was in the same league as the 6809..

One thing that I didn't get about the CoCo3: It wasn't compatible with either MS-DOS or most of the CoCo2 related stuff, yet it was a really nice machine? Tandy obviously wanted to try and the market to a higher level in 8-bit computing circles methinks..

Totally did not know about the enhanced 68k CoCo derivatives (the machines you referred to as systems IV/V) Good to see your old company (Delmar Co.) picked up the ball and make their own advanced CoCo derivatives after Tandy pulled out of that market! Really fascinating stuff!
