I've got a card out of an Apple IIe that has a bunch of 7400 chips on it,
a 4-switch dip switch, a 26pin header, and an EPROM with a label that says
"GPC" on it. The board also has "GPC" and "519"
silk-screened on the
comonent side and "Made in Taiwan R.O.C." on the solder side. Google
doesnt seem to reveal anything useful.
Any ideas what this is?
