I have a Qualstar 1260 (Pertec Interface) and connected it to a 
PDP-11/23 with an Emulex TC02.  It was fun to see it spin the tape and 
read/write data.  I could just imagine what torture it was to collect 
data or install operating systems that way.

Anyway, that's what it took for me to get the PDP-11 tape fever out of 
my system.  I think under RT-11 the tape was an MS: device.  If you 
could dig up a DEC TU80 drive it has a pertec interface and open rack 
space for a BA23 box.
