Sega Genesis - corroded RAM trace
A Model 2 VA1.8 Sega Genesis purchased off eBay as non-working presented as non-working. After several days of diagnosis, tracing and research into the system, I finally figured out that the problem was the corroded trace I identified right off the bat.

The Forklift Mac
Many years ago, I ordered a surprisingly cheap Power Macintosh 9500/132 off eBay. When it arrived, the box was completely obliterated, with a hole in the middle that looked suspiciously like a forklift tine. Naturally, the Spindler plastics were nothing but dust. The seller sent me a replacement machine, and life went on, at least until I had to clean out that room and found the box of broken parts.

Experiments in booting the A2500
Threw a few more hours at the A2000 today, cleaning up here and there. I popped out the 68000, cleaned up the pins, and checked the socket. The socket wipers are immaculate, not a speck of corrosion or acid on them (I checked with a magnifying glass). The pins for the socket on the underside of the board are still nice and shiny, so I’m willing to say the socket is alright.

Battery removal from the Amiga 2500
I’ve had this Amiga 2000 for several years, but it was only recently that I put in the effort to fix it. The big problem with these machines long-term is that the Varta clock batteries explode and corrode all the traces and sockets. Mine has a leaky battery for sure, so I hope I can save it.

Starting on the Amiga 2500
A couple years ago, I traded some car parts to a friend for his dad’s old Amiga A3000 and A2500. I knew that clock batteries were going to be a threat on both of those, so I nobly waited a year to take apart and desolder the battery from the A3000. That was back in 2014.
