Yes, these do, but none of the DA, DB, DC or DD types were 19 pins. In fact, as a 19 pin connector was a special just for Apple, it had NO assigned MIL-Spec designation at all, and was NOT any of the MIL- Spec sizes, A, B, C or D. The HD series, which came out after Apple's 19 pin connector was designed, could have provided the required number of connections within an A, B, C or D sized connector, but those were not then available. You can get 15 pins within the space of 9 pins, using the HD series, and proportionally more in the 15, 25, 37 and 50 size connectors. In fact, the smaller (than "DB-19") 15-pin size shell can hold 25 pins, in the HD series, and would have been more than adequate for the Apple floppy and HD20 application. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Vintage Macs group.
