I've had
an Epson HQX-10 with K-B and CP/M 2.2 disk for some
time but have never found a monitor for it. It has the 8-pin DIN
socket for both the K-B and the monitor.
Any idea what the monitor pin-out might be ?
If it's the same as a QX10, then the pinout (from the hardware techincal
manual) is :
1: +12V power output to monitor
2: Ground
3: Not used
4: Hsync
5: Vsync
6: Ground
7: Ground
8: Video signal
What the manual doesn't show is the layout of the pins, and there are at
least 2 conventions (one for each type of the DIN connector). I think you
may be reduced to identifying signals with a voltmeter and 'scope
(finding the power and ground signals would be a good start, the others
won't be that hard to distinguish).
See below for the QX-10/16 cable pinouts.

The same manual gives the specs of the monitor (and
schematics of the
monitor FWIW). They are :
Hfreq : 19.3kHz
Vfreq : 45.8Hz
(Dot clock : 16.667MHz, but that one doesn't affect the monitor).
Syncs are TTL level, the video signal is >4V for full brightness, 1.0-3.5V
for half-brightness, 0-0.8V for black.
