I've used Apple Cider Vinegar to remove corrosion on a severely corroded Mac SE/30 metal chassis. It does a good job. I followed that up by spaying primer. It came out great! Good luck!
I use my SE/30 as a file trafficker to get data from my PowerMac 6500 to my Apple IIGS. The IIGS has a network card, but I don't know how to get AppleTalk to work with it. So I shuttle data from my 6500 to the SE/30, and copy data onto a 3.5" floppy to feed the IIGS. :D

64MB of RAM (4 16 MB SIMMS) in Bank A worked, but I also had to have memory in Bank B, so I loaded it up with four 2MB SIMMS. The Mac recognizes the extra memory but I don't have the option to enable Mode32 (perhaps its an...
