On a lark, my ol' propeller headed beanie was whirring, again, today. Problem: how to use old IBM differential scsi reel tape deck to make reel tapes for antique unix.... Discussion: I picked up a perfectly fine looking IBM 9348-001 differential scsi interface tape deck from an AS400 box. I had thought of using a differential to single-ended scsi converter, but, they are a tad dear for this olde man's beer bellie peanut computer budget. Thinking there had to be some other way of making use of this deck to write some fine old reels, I saw, buried deep in the pdp-11 cards list a differential tape card by Dilogic, and though... hmmm, can the old MVII crank out to the 9 track via such a card? Solutions: anyone have any insights on trying something like this or know if such a shennanigan will work? Are there any other such differential scsi cards available that might work? Anyone got such a critter gathering dust? Is this really a scsi card or is it some other interface? Thanks Bob
