If this is a SCSI QIC drive, I'd suggest moving to DLT, 8mm or even DDS. None of these suffer from the "broken bad" problem. SCSI tape drives as a class, are pretty much interchangeable as there's an ANSI spec for the command set. If it's a QIC-02 interface, you might want to look into emulation using an MCU. QIC-02 interface is stupid simple and any moderately capable MCU should be able to generate the required signals. You can probably fit the contents of every QIC tape that you own on a single SD card. QIC-36 is going to be a bit more difficult, but there were (and maybe still are) QIC-36-to-QIC-02 bridge boards around. My .02 for whatever its depreciated value is worth. --Chuck
