Looks like you used a PC-type twisted pair for dual-drive motor control capability, but with the drives reversed so that a single drive would use a straight cable; makes sense. I suppose on a PC they did it the other way so that the terminating resistors would always be on the cable end, even if using a dual drive cable with a single drive, but that's not particularly relevant in a 'custom' 1581 and not usually an issue anyway in the 'real world' (at least with floppies as opposed to hard drives). m Message was sent through the cbm-hackers mailing listReceived on 2016-08-23 18:00:40
