So, I'm trying to fix up those 5 systems I came across in my garage, and I'm noticing that the edge connector on the Sega CD side on almost all of them is worn down or corroded in some fashion. I haven't tested them with a working Sega CD yet, as my laser needs to be replaced on my own unit, and that's the only console I have for the test. However, I've decided to go ahead with the repairs and mods of the units in the meantime, and I was wondering if anyone has tried to repair the edge connector, and if so, what worked best for you? I'm considering adding a small amount of solder to cover the contacts, but I'm worried it might push out the Sega CD connector pins in the long run.
Anyway, suggestions are welcome. Thanks.
