Well, in my travels today I purchased 2 Apple IIgs units from a retired Music teacher (very nice lady) and a midi card, and tons of software + an Imagewriter printer all for $100.00.
I am beat today, so I just went through it quickly. I will take time next weekend and take some photos and post them.
One of the IIgs (hers) is almost factory new. She took real good care of it. The other was a spare her husband purchased at a yard sale for a spare.
Anyhow in my quick look and the motherboards (they are both ROM1s) the yard sale one looked like a normal IIgs motherboard.
But, her machine, The motherboard had not only the IIgs connectors on it, but it also had all the IIe connectors too. (The IIe power connector, Keyboard Connector etc.)
Could this be a IIe to IIgs motherboard that was put in the IIgs case? A service replacement perhaps? or Did some of the ROM1 IIgs boards come that way?
I will continue to investigate and as I said publish pictures next weekend.
Thought I would share.
