I have been looking for an accelerator card for awhile now. I am not about to (nor can I afford) an ebay priced TranswarpGS. People had told me "just check some IIGS systems and you might get lucky", but good luck with that. I can't even find IIGS systems to check! I lucked out bigtime with finding one locally (a mint ROM3 version) and finding an affordable CFFA3000 so I really cannot complain....but damn man. You open the first IIGS and find one? If you find one in the five other machines you obtained I give up.
