Easy enough to tell without opening things up.
The tape interface I have for my UNIX PC is indeed a floppy tape interface,
says "FTAPE" near the connector on the outside. I haven't paired a drive
with it yet.
Thanks,

Yes, the 7300/3B1 was officially the "Unix PC". My point was that the
3B2 notes say that particular system used the Cipher 525 floppytape and
was 23 MB capacity. This agrees

Hi,
during my move, I think I lost my tape drive, which was attached to my
at&t unix pc (68000 based).
Anybody knows of the top of their head, if I could read the tapes on any
other machine? Was it anything "standard", or did they do their own at at&t?
Cheers & thanks!

Well, I don't know what happened to everybody who wanted it
but that Unix-PC is still sitting here and it needs to go. One more
offer before I scrap it. Needs to be someone who can pick it up
real soon.

As I mentioned elsewhere, I worked on software for them at Burroughs
('86-'89). I picked up a bunch of B25 stuff in '03, but I could never
find any software for them. In retrospect, I wish that I has stashed
away B25 (and B1000 (I was one of the last people in the office

Are there any better pictures around of the B20/21/22 ? If not, I think I still

You're right, the machine I owned is the one I see from your link. The
workstation you mentioned is in the same box but with a monitor and the
location of the clips and led slightly different.
But I was not far ;-) I don't remember what kind of hardware was exactly
in this machine. Shame on me,
