Apple IIgs Find!

I just received an Apple IIgs with some cool cards and I'm looking to see if anyone has doc or software for these. The machine is a: Apple IIgs Rom 3 (But with a Woz signed case) Apple IIgs Memory Expansion (1 meg) Transwarp GS Apple II Video Overlay Card (This was the main card I wanted!!) Applied Engineering RamKeeper Battery which seems to go to a small card attached between the PSU and slot 1. I think this keeps power to the Ram. 2 3.5" drives 2 5.25" drives Keyboard & mouse ImageWriter II Printer But no doc or software for any of it. I'm interested in anything people can tell/send me on the Video Overlay Card mainly but also the Transwarp GS and the RamKeeper. Thanks in advance. ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com
