I used to pick up junk for nearly free or free - I just looked in the 
closet and found:

Hitachi Terminal Adapter ISDN
T94-5042-0
Manufactured in April 1996

On the back it has what looks sort of like a serial port (slightly 
different size though) with "X.21" below it.  Next to that is a larger 
and very strange looking plug with "V.35" written by it.  To the right 
of both of them is a LAN jack.

Mechanically, I don't think I'm ever going to find cords for those weird 
plugs... I guess I should just toss this in the trash?


Another bit of hardware I have is:

Nortel Networks, Inc.
Model AXM-D-8-S-173
MLB 301250-A  REV 02

This one has a bank of 8 LAN ports, and then another LAN port and an odd 
plug (like the one for the Hitachi) with "TRANSCEIVER (AUI) written 
between them.

A couple of manuals that came with it say:

Bay Networks
Micro Annex
Hardware
Installation Guide

and

ANNEX Communications Server
Xylogics
Copyright 1990
Xylogics, Inc.

By appearances, it looks like it could be used as a sort of hub... is 
there a useful application for old equipment like this?
