Yup, Motorola kept reducing the instruction sets down to 27? on the

it's messy internal architecture. People writing code for Intel hated
it!

Then came along the Z-80 with it's block memory move in one
instruction. Trouble was, that a 6809 with code for a memory move
loop could move the block faster and with less setup instructions
and time.

We all learned the long and hard way.

I always thought the Nat'l Semi 16032 and its relatives had the best
instruction set of the micro chips, but my real favorite was a
mainframe from the '60s, the GE4xx series. Not a lot about it on the
web but a little at:


Mixed thoughts there Larry 0 GE4x was not a microprocessor based machine.
