I'm at wits end. I've replaced every chip on this card except the M5832 and I can't get my IIe or IIgs to see the card. The 3 disk images I've tried all contain the same thing and RUN TIME.NO.ROM renders garbage.
What am I doing wrong?
Solution:
Druid gave me an idea and I ran with it. I took the ROM from the timemaster card and plopped it into a parallel card. Boom. It was recognized as a timemaster. I replaced the ROM socket and the LS00 and LS08 logic sockets and the card now works.
Bad sockets were the source of this weeks insanity.
Go figure.
As a side note: The GND lines from edge connector on this card had some hairline cracks near the edge connector. In case someone else sees this and is trying to repair it try looking there too.
AND - There is a picture of this card with a Z80 CPU, PAL and SRAM - That is not a Timemaster II H.O. - OR it is a modified Timemaster II H.O.
