Applied Engineering Transwarp GS or TWGS
AE said it best! Computing at Warp Speed. It’s an experience you shouldn’t miss. And definitely a must have for every Apple IIGS user. There are still many modifications available for this card - some report speeds of up to 18 MHz.
Pulled from a working ROM 1 IIGS, this TransWarp GS Accelerator works great! I think it is an original, unmodified card, so it would be 7MHz. Also included is an original User’s Manual.
