Through sheer luck a friend of mine gave me this IIcx (battery not exploded).
It has an Ethernet card (Asanté MacCon+ II E thick and thin) and a Supermac (unknown) graphics card.
It also came with a 256 SCSI drive.
With what can I replace the battery? Do I need it to run at all?
Have you recapped the board? Usually the PSU is fine (besides also needing a recap) but the issue is with the large axial caps. If they're not good then the soft power from the power supply won't work. And usually the PSU recap is super simple.
Plus it already is going to need a recap, all those old electrolytic caps fail.
Too late 😞… At least it’s going to be stock looking
