IEEE-488 on the PDP-11

[Douglas Taylor via cctalk]

In my pile of DEC computer stuff I have a DEC qbus IBV11 IEEE-488 
controller board (M7954) with cable (BN11-A) that connects to the GPIB bus.

It would be interesting to try this out, but I don't have the DEC 
'Instrument Bus Subroutines' that work under RT-11.  Does anyone have 
this package?  Or know where it can be found?
