[Techtoolslist] Fluke & Midway 8080 boards...

[John Robertson]

Anyone remember what is needed to get valid memory reads on the 8080 
boards? I seem to recall one has to set  the gates to a state prior to 
doing a ROM test, but can't recall the process...perhaps someone has a 
script they can share?

At the moment the RAM test works fine, however any ROM space that has FF 
in it - on the high memory area (FFXh) gets random garbage inserted from 
the injection of some clock info on the data buss. The valid data 
locations in the ROM dont' appear to be affected. Tried adding a pullup 
resistor bank, no change. No ROMs, no change...

Thanks!
