If anyone here needs or wants some Xylogics Annex Three boxes (64 serial 
ports per box), I've got at least two available, with some of the 
serial breakout cables.

Another option would be a DECserver that does reverse LAT, or a Xyplex 
terminal server, which is very much like a clone of a DECserver, only 
it has telnet capability in addition to LAT (and telnet is a nice thing 
to have ;).
