Does anyone know if the above is identical in spec to the "official" Zilog PIO
chip? The manual's dated November 1976 and stamped as preliminary, which is
a little unsettling :)
I want to do some messing around with a Z80 CPU and PIO, and having a physical
paper reference to hand would sure be useful - I'm just not sure if I'm going
to shoot myself in the foot using this particular one!
I should go and google for Zilog / Z80 history I suppose to see where Mostek
fit into things - I've got a rather thick Mostek UK Z80 programming manual
(V2.0) too which would also make a useful reference, assuming it's sound for
all Z80 chips regardless of source...
cheers
