Hey!
Has anybody got good logic analyzer pictures of the signals on the S-100
driven by the really early 8080 CPU cards? I'm looking to get a reference
document for that signal set so I can approximate it with signals derived
from a Z80. I have several "middle-period"
cpu's, but no 8080 CPU cards
from the pre-Z80 days. I can make my own pictures from the middle period
(early
Z80) CPU's, e.g. CCS, SD Systems, etc, and I have a couple of '696
standard CPU's as well, though they're quite different one from the other.
I anybody has, or knows of such documents, please let me know.
Dick
