I have updated the first post with scans of the card's bare PCB (from the non-working one I received) and a components list
note:
Did my best to describe them but:
a. not sure if the 2 resistor network descriptions are fine though - I believe they are COMMONED and not isolated networks , I get the same resistance in each pin only if the 1st one is the common pin in each measurement edit: 220ohms one is isolated not common
b. the PAL-16L8 IC has the "read protection" bit enabled, so there is no way for me to read it 🙁
I hope this extra info proves helpful in repairs , if you think I can add anything more or help with component identification please say so 😀
I plan to solder sockets on the bare pcb and replace all ICs and passive components on it, if the PAL is not the problem then I think the card will work again 😁
