What is it?

This simple board will allow you to convert a 50-pin ribbon SCSI-1 connection to a DB-25 SCSI-1 connection.

This was originally intended as a method for the PiSCSI to daisy-chain SCSI devices. However, it can also be used as a general purpose SCSI adapter.

For example this can be used for connecting an internal SCSI-1 drive to an external SCSI port. (You'll have to provide your own power)

What makes it special?

It's cheap. It's simple. It's easy.
