find I had a
few to sell.
There were also a couple of microprocessor "trainers" that used them,
but, no, it never saw general application. I suspect that the 32K
memory limit put it at a distinct disadvantage, alhtough the
instruction set was pretty decent. I'm really surprised that it
wasn't used more in terminals.
The 2650 has to be one of the interesting oddball cases in that I'll
wager that far more 2651/2661 USARTs were sold than 2650 CPUs.
