Possible Anode Driver replacement
Hi everyone,
while repairing some HP65s, I have noticed that one of the common failures in these calcs is often
the Anode Driver.

Searching on the Internet and keeping in mind that it should work with the LED module 5082–7415

I have found out this device Motorola MC144898

Does anyone thinks is worth a try ?
It may have a different pinout but this is something that could be adapted

Please let me know your thoughts
take care, Alberto

Edoardo & Alberto
