SCSI Cable

One of the recent purchases that I did was a Phase 5 Blizzard 1260 with the extra Blizzard SCSI Kit IV that has an extra slot for adding up to 128MB extra RAM. The SCSI-connector that is on the add-on card is a IDC26-pin where only 25 pins are used.

What I can see online, the original cable has a 25 pin Centronic on the other end but I do not want to use an external SCSI HDD. I started to look around and I finally had collected the needed information so I could build my own IDC26 to IDC50 SCSI Cable.



It was not very hard to make this cable, the important thing was to have it correct the first time so I would not by any chance fry my card. Below is the connection scheme that I summarized. A short description is:

  • IDC50 = Connector pins on the IDC 50.
  • IDC26 = Connector pins on the IDC 26.
  • Name = Short name
  • Direction = Direction of the signal, directional or bi-directional.
  • Description = Long name.
