G'day All, long time lurker, 1st time poster!
So I got a lovely little LCIII a while back which had leaking caps and I've decided to restore it. I love these little machines, they remind me of the Centris 610 I had back in the 90's (although that was a 68040). It was actually working but if left any longer it prolly would have succumbed to corrosion damage.
The Mechanical dirve also died shortly after I bought it and has now been replaced with a SCSI2SD flash based Drive.
I've also dropped in a 68882 FPU and upped the RAM to 36MB ... I also found a 256k VRAM SIMM on eBay for a price I could live with and will install that shortly.
Anyhoo onto the fun part, here's shortly before I removed the caps - the most obvious damage is to the PCB near the battery (caused by the cap, not battery).
Bad Cap! (1 pad completely gone and both traces, not too hard to repair tho)
and the other bad cap! (lucky no real damage tho)
and all dodgy caps gone:
and repair in progress. I haven't fixed the missing pad yet but the other side had trace damage (easy fix) - I suspect the missing track was direct linked to a ground plane but haven't finished checking my theory yet:
Side A:
Side B (a bit neater than side A):
and that's it for now folks, Im just waiting for my new caps to arrive from element14 before I can finish it off.... oh and im going to replace all the caps in the TDK power supply just to be safe.
