SCSI 25 pin adapter to USB or Firewire needed

You'd probably find it much cheaper to get a mac with both ethernet and SCSI and transferring files across the network to your new systems.

Lisa Jane,

After finding the cheapest adapter, namely an older Mac, do not forget to open files and save them as RTF or other generic formats that can be opened by newer software.

Lisa Jane -

A neighbor with an old Mac would of course be the cheapest option. There are a couple of transfer services out there, but shipping the heavy drive will probably be expensive:

The "standard" first cable from the DB-25 that was used on the back of older Macs to the Centronics-50 that was used on earlier drive enclosures is called a "Mac SCSI System cable". The cable connects the roughly 5 grounds available at the 25-pin end to many more in the cable that are connected at the 50-pin end, such that each signal can be twisted around a ground for good quiet performance. If you ever find yourself needing to go back down to 25-pins to pick up a 25-pin device at the end of the chain, that cable can be used facing the other direction.

The 50-pin connecter that is about the same overall size as the DB-25 is called the HP DB-50. The HP in this case, does not actually refer to Hewlett Packard, but Half Pitch, meaning that the distance between the pins is half the dimension in the standard DB-connecters. These cables, and the terminators used with them are a little more expensive than Centronics-50.
