Test-ok, thanks but that's not the boat anchor I'm after. Further info, the ps cabinet is grey and the KSU is black. Long story short, don't ask why, but we put in 11 AFTER they were declared manufacture discontinued about 1982. Sucker was huge, roughly 3 feet by 5 feet, and 18 inches deep! 30/60 expansion added about 20 inches to the top of the 20/40 cabinet! Each station card supported 1 station! Roughly 14 X 14 inches! C.O. cards were about 6 X 14 inches! Every phone was a speaker phone and you could actually have 2 different conversations, 1 speakerphone, 1 handset, at the same time! Supposedly the design was financed by the great state of Mass. as a "make-work" program, in the late '70's. It ran on random lay quad and there was no audio on either pair. Maybe the 1st fully digital system to be deployed, about 1978? And DO NOT ask about crosstalk trouble shooting! frown John C. (Not Garand)

When I was young, I was Liberal. As I aged and wised up, I became Conservative. Now that I'm old, I have settled on Curmudgeon.
