And I've seen "boxy transceivers" recently in some network suppliers catalogues (but in the UK, which might not help Ethan). And they were pretty expensive in the catalogues (rarity value, probably). FWIW, all the ones I've seen which used the removable type of tap, had the same fiting, so my BICC, 3Com, and Cabletron transceivers and taps are interchangable. I never had any vampire taps (hint: I want one for my display) but I wouldn't be surprised to find they were interchangable too. If you didn't know, there are two screws visible near the top of the transceiver; take those out (they're quite long as they go almost all the way through the body) and the tap part should come off quite easily. The screws don't screw into the tap, they go through holes in it and screw into the rear of the transceiver body; they are only there to stop the tap falling off (or in the case of cables of the floor, to stop the transceiver falling off the tap it's hanging from!). a and use Yes, that would work. Some of my taps have an N connector on each end, some have a sort of BNC T-piece, and some just have a single BNC (bring your own T). N-to-BNC adaptors are fairly common and cheap. I don't have an operational 10base5 segment at the moment, but I do have all the bits, and I do use some of the old transceivers (with BNC fittings or adaptors) and real thick blue drop cables for my Vax and '11s. If it wouldn't cost so much to ship, I'd trade some of my thick yellow cable for a vampire tap :-) -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York
