I am the proud owner of a 3192G coax terminal.
As I have recently learned, there is an expansion module for the
terminal that allows you to attach a mouse and a IEEE-488 pen plotter to
the terminal. Some information about it can be found at  and .
I am searching for people who are in possession of this expansion unit,
out of interest how the PCB looks, etc.
If you have one, please respond.
