In working on an Apple to USB interface, I've found this document very useful for pinouts of various Apple II components:
http://mirrors.apple2.org.za/apple.cabi.net/FAQs.and.INFO/CablesAndPinouts/A2.MISC.PINOUTS.TXT
most notably the IIe keyboard matrix.
I've worked out most of the matrix for the IIc with a multimeter and trial and error, but I've got a few weird overlaps. I wonder if there's a document anywhere that has the full pinout for the IIc (and maybe IIgs as well).
Any pointers?
