Tek 500 pulser modules

[Jon Elson via cctalk]

I have 3 units of the Pulse Instruments PI-451A programmable 
pulse driver.  One has a note that it is bad.  These seem to 
be general purpose pulse generators, capable of +/- 25 V 
into 50 Ohms (but that is just from reading the labels on 
the panel.)

Anybody have a use for them?  If I had a 500 bin I could 
probably use them, but I don't.
