I have one in my main IIgs. The power supply has a mounting position for the fan on its side, and there is a power connector on the motherboard for it (+12V). > If I may ask, what is the good of all the IIe connectors on my IIgs board? For use in an upgraded IIe. Apple supplied a kit that allowed a IIe to become a IIgs. Of the original IIe, all that is retained is the upper part of the case (including the lid), the keyboard and the power supply. The base plate, back panel and motherboard are replaced. A IIgs sticker was included which was stuck over the IIe logo. > Oh yeah, and I shouldn't even bother plugging the keyboard plug from the > PCT into that keyboard socket, right? The card will sense the IIgs ADB > keyboard and enable it accordingly, correct? Correct. If the PC Transporter software detects that it is running in a IIgs, it uses the IIgs keyboard registers to access the keyboard. This works with either the IIe keyboard or an external ADB one, but using the IIe keyboard has the same limitations as normal (the numeric keypad, if any, is treated like the corresponding standard keys). The IIgs has a register which allows all the modifier keys (Ctrl, Shift and Caps Lock) to be sensed directly. This is the only useful function provided by the PCT keyboard adaptor in a IIe, so it wouldn't achieve much to use it in a IIgs. -- David Empson dempson@actrix.gen.nz Snail mail: P.O.
