RE: HP 9872T Trouble Shooting
By the way, the 9872C schematics seemed to show a discrepancy with the mapping of some of the address bus bits to the ROM address pins. I'm not sure if this is real or not, as it also showed the ROM enable signal (labeled as "F1") going to an address pin on the 36000 ROM instead of the CE pin.
