This is the listing of the CNC boards that Ive got for sale. Perhaps
some of you can tell me what they are, what they are worth, etc.

Gandalf , RM3120E

This is an asynchronous limited distance data set, in a rackmount
configuration, made from th emid 70's until perhaps the early 90's. It was
likely used to extend the serial port from a controller to a controllee
(RS232 serial port devices are limited to a few hundred feet, or 50' by
spec, while these puppies will drive a signal a few miles over 2 pair wire).
These are proprietary Gandalf technology that will only talk to another
Gandalf 120 or 140. I think that the E stood for Europe, as in 220VAC/50Hz,
but I could be wrong. Gandalf was from Ottawa Canada, and is no more. You
can get similar units for $50 each brand new (Patton, RAD, Black Box, etc.).
My opinion is that they are junk. Of course I used to work for Develcon, a
direct competitor of those purple monsters at Gandalf : ) Seriously though,
they are likely junk, and not very special at best.

COOL! One identified! Thanks!!

which thinks that nothing is worth war is much worse. The person who has nothing for which he is willing to fight,
nothing which is more important than his own personal safety, is a miserable creature and has no chance of being
free unless made and kept so by the exertions of better men than himself."
