Yep, meanwhile I read the drive hack hint in the Catweasel manual you mentioned. Hmmm... Putting a LED beside the photo resistor... Checking 'MOTOR if it's active, and if it is, and there's no 'INDEX, start flashing, does it sound like a good idea? ;-) Also... A really weird idea has popped up in my mind, regarding the 100tpi / 96 tpi problem. Pulsing 'STEP by some 100kHz, and rotating a 8-chain PWM bitmask on the 'DIR pin, hmmm? ;-) (I know different drives would react differently, and it would also need additional attention of the software, but still this should be the only possibility to make it (if at all)).
