DEC keys and consoles

Does anyone know of a good source of the "ubiquitous" DEC keys, specifically one of the normal keys (for a PDP-11/10) and one of the cylindrical keys (for a PDP-11/24)? Otherwise, if anyone has a stash of spares or is willing to make duplicates, let me know. Also, I'm looking for information on connecting a console to the 11/10. The only place on this machine that looks like a likely candidate for console connection is a double height module (an M9970 Berg backplane connector) that is essentially unpopulated except for traces connecting the backplane to a single Berg connector. Is this the serial interface? If so, are there any configuration options (on another board), or am I stuck using what I assume is a fixed 110 baud 20 mA current loop interface (or digging up something else, such as a DL11-W)? -- Scott Ware s-ware(a)nwu.edu
