Wanted: PC11 interface

My PDP11/40 had a high speed paper tape reader/punch when it was new 
(PC04 I think). I have the hardware, but not the Unibus card. I think it 
failed and was replace with a Facit punch with a serial interface.

So, does anybody have a M7810 they want to get rid of? That is the PC11 
interface. I don't know if that is a quad SPC board or a dual that needs 
a M105 address board and an M7821 interrupt board. I think it needs the 
extra boards.

Any lead or information is welcome...
