IBM 3725 Communications Controller

Am I the only one that acquires hardware for which I don't (yet) have any useful way to hook it up? I mean, I've got graphics accelerators for Sun/DEC/IBM workstations where I don't have the card that goes into the host, or even a host to hook it into. I've got an HP graphics generator and no oscilloscope to hook it up to. I've got dial boxes and tablets and no machine to hook them to. Eventually I hope to fill in the missing pieces, but given that the pieces I have already are hard to obtain, that may be impossible. I have an offer of an E&S Picture System II monitor. Not the whole terminal, just the monitor. Sure, I'll take that. What's so wrong about rescuing a piece of classic equipment for which you don't currently have anything else that goes with it? Nothing in my book.
