- BZZZT.

- 3/80s don't have internal transceivers, and there's no way to just take
- the 15-pin ethernet ports of the 3/80s and wire them together. (Are there
- any electronics wizards out there who'd like to say otherwise? Maybe it's
- possible if you only have TWO workstations?)
-
- Clearly, Steve Aliamus wants to avoid spending the $60-$70 or so each for
- a pair of ethernet transceivers, or else find a source for the cheapest
- possible transceivers.
-
- Steve: you're probably going to have to fork over the $$$ for a couple of
- 15-pin to coax transceivers. Most companies, as they upgrade their networks,
- are going from older v-tap transceivers to central twisted-pair hubs, so
- there ought to be a growing supply of junked transceivers...the trick is
- finding 'em. If you have connections with anyone who works for a company
- that does mega networking, you might be able to scrounge a couple of old
- vampire tap transceivers and a hunk of RG-8 (thick) coax cable, stick on a
- couple of terminators, run 2 lengths of transceiver cable into the 3/80s
- and you'd be in business.
-
- I saw an ad from Allied Telesis for $69.95 for a slim-line 15-pin to BNC
- (thin net) transceiver. There are probably others, I just happened to flip
- to that one on a cursory glance through SunWorld. You can call Allied at
- 800-424-4284. Two transceivers, plus the afore-described collection of
- thinwire, T connectors and terminators would put you in business for $165.
