Any familar with "Disk-A-Tape"?

Is anyone here familar with a device called Disk-A-Tape? It's paper tape emulator that uses a HH 5 1/4" floppy disk drive. (The drive is mounted in a filler plate that fits in a mount for a HH 8" floppy drive). It mounts in a 19" rack and is about 8" tall and 12" deep. Besides the drive, it has a reset pushbutton, an Init/Job toggle switch, FWD/Rev toggle switch, Read/Write toggle switch, Emulate/Off/RS-232 toggle switch and a small 8 digit LED display and an AC power switch on the front panel. On the back it has a DB-25M and DB-25F connectors. There are two circuit cards in them, one small one and a larger wire wrap card. I haven't taken it apart and looked at the ICs on the boards yet. I picked up two of these today, mostly out of curiousity. They came out of what looked like some kind of CNC machinery controller. There was also a DEC PDP-11/04 in one of the chassis. BTW I was searching the net for info on this and found this <http://www.fastec.com/xdisk/> instead. Interesting but I'm not sure it's it's related to what I have or not. joe
