I picked up a two-port parallel card for my Lisa 2/10. Unfortunately, it
fails the POST diagnostics with error '92'. The system does correctly
identify which slot it's in, FWIW.
Does anyone know what the system firmware is poking around for? Is it
asserting a checksum test on the card's EPROM? Checking for an interrupt
response?
The label covering the parallel card EPROM erase window is long gone, so
I'm wondering if it was left in the sunlight and partially erased.
Does anyone have an image of the EPROM?
