My geometry problem actually seems to be the CRT itself--the lower-left hand corner is pushed in somewhat, making text appear slanted in that area. Resolution isn't an issue for me, it's the hardware itself.

As far as the keyboard--if I had an extra IIGS keyboard I'd probably use that instead (both for the "authentic Apple II" feel and the clickiness). I don't have the room for an Extended II (which I would have liked to have used) and don't have an extra standard ADB I keyboard. Does anyone know of any good space-savers with a clicky feel just in case I can't find another IIGS board?
