I have a drive and controller that Don Maslin gave me
supposedly from
a Tek terminal of some sort. It's a Wangtek drive and a like-sized
controller board with an 8085 on it. Interfaces on both ends are 50
conductor--if the computer side was something like SASI, it wouldn't
surprise me--I've never had to use it. The pinch roller in the drive
is in pretty bad shape now, though that could be dealt with without
too much trouble, I imagine. I wonder if the drive-side interface
isn't QIC-36, which would mean that there are PC-based controllers
available for it.

The tape drive in a 405x predates QIC. The head is fixed in place and
uses one track for clock and one for data. It is more similar to digital
cassettes than the later QIC drives.
