[sdiy] Microcontrollers

[Bill Keys]

Right! Now I remember - Z-80 in the Prophet and 8048 in the Poly61!! 
Thanks!!! At one time I was going to cannibalize the Poly61 and was wishing 
it had a more familiar micro; but didn't want to tear up my Prophet even tho 
it was a Z-80.... (well, unless it was _completely_ dead....)

+_+_Yes, honey, I know there are 25 boxes of electronic junk cluttering up 
the attic. They will, one day, magically be transformed into a modular
