Hi folks, quick update after having replaced the chips by F series : the board now appears to run fine in partial match mode up to 6 MHz. With a 8 MHz oscillator, the board hangs when loading CP/M but this is certainly the limit of my passive backplane. I have soldered three connectors on the 8 slot active backplane PCB I already have, I will populate it with the necessary components and run a quick test, until I get the terminator board or the 18-slot active backplane.
One problem to investigate though : Querying unused IO ports from the monitor still returns values different from FF, so certainly something's wrong somewhere... -- You received this message because you are subscribed to the Google Groups "N8VEM-S100" group.
