When I was debugging the connection between my VAX and

3.5" floppy drive! ;)
HP 4952? I have two with tapes from the old days (they contain a
formatter, and we did wipe some scratch tapes for storage of our
analyzer programs, including a PU Type 2 BIND simulator that filled
the program memory, but it worked well enough for us to debug SNA BIND
sequences in the absence of a real PU Type 4).
