i am interesting to make a scsi cable to connect a scanner that have a centronics 50 pin and/or a db25 with a pc ibm over controller 68/50pin output.
where i can see a wiring scheme for this cable?
You would be better off buying one from your local cable guy or eBay once you decide which connecters you have.More for reliability purposes than cheapness.
I have used idc cable for an external application once,did not look pretty but it did the job for a while,buying a centronics 50 pin idc and a scsi 68 idc female.
Does your scanner have selectable termination,if not you will have to provide it,that is if it is last in line.
Hope this helps
