Seems odd though; since the 900 has provisions for two drives (DS0 and DS1) how would a dual-drive system be configured? Nevertheless, in the 1581 pin 10 is grounded while pin 12 is NC, which does suggest that the 1581's drive should probably be set to DS0... m Message was sent through the cbm-hackers mailing listReceived on 2016-08-23 17:00:14
