what--if it aint on the web,it is not???

refer to zilog data book dc8321-00

to have separate code/data is inhibative---and adds to the complexity.
a better machine has no such distinction because of the obvious.

it bit ya once above--remember to ff the pig.,oh the loop is a
run power-up only?
you disdain tru bi-di?
who came out with 8080a???

there is no such thing as a "trick" with microprocessors...only logic.

so if the core is so unimportant to you,why the (failed) attempt
to rebuke my conclusion the aduc812 would be a better machine
with a z80 core...the low level is where its all done,and you
rebuke that too.rather use a drill to make a hole in a block of
wood than a screwdriver---have done both and know what is
better.
