The console terminal connection maybe labeled directly on the backplane (a
row of ~10 pins), only 3 pins for the RS232 are needed. I guess you don't
have the info. to the pin outs?
Dave, what part of the world are you located in?

an external terminal. This replaced the paddle switch
functions of the Nova 3.
George, thanks. If the Nova 4 Jr. CPU is marked 'DCG JR. CPU' in the front
right-hand corner (and it's a pretty good bet), then that's probably what I
have and I'll confirm by looking for those memory chips.
Am I right in thinking that the console terminal connection is made through
pins on the backplane as there is apparently no socket on the board for this
purpose ?
