GTA digital dash schematics
Hi,
Does anyone have schematics of the circuit cards in the GTA digital dash? Preferrably the odometer card.
My problem is with the odometer display, it simply flashes all 9's along with the rest of the odometer LCD (which also flashes as if it's stuck in perpetual reset). The service manual indicates that the EEPROM should be replaced, however I don't have a spare.
I've reseated the EEPROM, all the boards and all the LCDs in the dash. The rest of the dash works. The best I've found so far is the datasheet for the EEPROM, which is NCR 52801. If nothing else, I'll at least verify that the EEPROM is getting VSS, VCC and ground.

Some old posts reference this site:

However it's a dead link now? Maybe someone visited this site years ago and saved all the stuff?
