IIgs ROM 3

["Paul Grammens" <grammens@svn.net>]

Thanks for all those tips on how to spot a ROM 3 IIgs. I went to a sale of
highschool surplus stuff, and went thru a pile of junk that included some
IIgs's. I felt like a pearl diver, popping open IIgs after IIgs. Finally,
there was the pearl: a battery clearly visible beside the powersupply. I got
it for a buck. The mb works! Interestingly, the P/S doesn't. I opened it up
and noticed some severe corrosion in a few small spots on the underside of
the circuit board. Looks like they had some process problems when the raw PC
bd was made, left some chemicals on. May be able to clean it up and make new
traces with copper wire, and resolder. I really wanted one of those high
power supplies...
