Anyone have a QIC-100 SCSI tape drive drive? Or know where to get one?
Seems like there was a brief window when such a thing existed, but I
can't seem to find any evidence on the web. I must be searching for the
wrong thing. I probably need a specific product.
I've got a qic-150 drive (the large 4x6x.5" carts). I need a qic-100 drive.
(I suspect it's the same size cart as a TU-58. I don't plan to use it to
read TU-58's, but who knows, maybe it will read them)

Other Google searches turned up articles in InfoWorld saying the format was
developed by Tallgrass, which explains the ASIC with their name on in inside the
3M/Apple tape mechanism I have pictures of on bitsavers/3M and that Gammamat is QIC-100
At least the on-tape format is documented in the QIC spec.
