I have a BMS-200 Atari to SCSI adapter card. It has the traditional 19 pin Atari Cable connector on the card. It also has the ability to link (daisychain)to another external scsi device using another 19 pin connector on the card. I have another external SCSI enclosure with a HD 50 pin connector. Where does one find the cable to go from the Atari 19 pin connector to a HD 50 pin scsi connector or a 25 pin connector?
