Hi Joe: Here is what I have on the IIc and Laser128 as they were the
same. I took this from a larger posting that shows all the Apple II
series Serial connectors from DB25 to the newer Mini-Din8 connectors
plus their signal identifications. This happens to include the IIgs
RGB but not the IIe RGB info I am presently tracking down to update
this part of my file. If anyone is interested I can post the entire
serial connectors with pin outs. Gene. K7EEK
Apple RGB Connections
The RGB port on the IIgs has the following output: This is not the
same for the Apple IIe. I do not have info on the IIe RGB port and do
not know if the IIc RGB port is the same.
The Apple IIc and Laser 128 are also shown.
