Re: HP 150 Touchscreen II repair
That's the HPIB version of the printer. The microcontroller used has an internal HPIL interface, the HPIL model simply brings that out to the rear panel via the normal transformer, etc. The RS232 and Centronics models have internal interface boards that communicate with the microcontroller over a parellel data bus.
And the HPIB model? Amazingly it the same microcontroller as the HPIL version with an HPIB-HPIL interface board. Something like an HP82169 with different firmware.
I hope I am wrong, but that flexiprint is probably corroded and will be open-circuit.
