The other card is for the standard slot. Very likely it is an RGB card, but would require at least the video signal (not present at the slot) to work. I suspect J4 had a cable connected to some chip on the motherboard. Or maybe J1 should be connected to the video signal.Yes, as I said above, I was wondering if the 2-pin connector (J1) was for that purpose. As for J4, you may indeed be correct. Without some documentation or informed opinion from someone more knowledgeable, I am hesitant to just plug things in haphazardly I don't want to fry my IIe.
A very sound approach. A lot of electronic equipment has been rendered junk by random plugging. ;-) One of my (not) favorites was a boxed single-board computer, intended to be operated on 12v, that someone "tried out" with 115vac! ;-( Destruction was so rapid that aside from a couple of chips with their plastic tops detonated and a bunch of "ghost" components with little beyond their leads left, there were no burn marks on the board! -michael ******** Note new website URL ******** NadaNet and AppleCrate II for Apple II parallel computing!
