Head-desk-head-desk-head-desk . . . :I
OOPSIE!!!! When I was up late last night I misread the schematic for the IIsi and never actually counted the lines.
I just put red lines emanating from the proper legs of the MDU in my AI file, counted them to cross-check . . . and came up with too many!
TEN address lines and the W/E line were what I counted for a total of eleven. Took a gmuch closer look at the schematic again and realized it said "A0-A9" NOT "A0-A7" so much of my concern just vanished.
You may have enough address lines for al's bigchips to work in Bank A of the IIsi, uni!
