Can anybody tell me if a "proper" (i.e. true IBM compatible) CGA (CGA, not
MDA, EGA or VGA) monitor had a male or female connector?
I know it had a DB-9 with approximately this pinout
1,2 Ground
3 Red
4 Green
5 Blue
6 Intensify
7 N/C
8 Hsync
9 Vsync
All signals are TTL and active high, as I remember.
Anybody in the SF Bay Area got a real CGA monitor that they don't want
anymore?
Thanks,

All of the CGA cards that I can recall seeing had female connectors, so
most likely, the monitors have male connectors.

That only implies that the *cable* has a male connector on one end; it
doesn't really tell you anything about the monitor.
I'd be inclined to expect that most CGI monitors either had a captive
cable, or had a female connector on the monitor as well. But it's been
so long since I looked at CGI monitors that I don't recall.

The cables (both data and power) are captive. And yes, there's a male
DE9 on the data cable from the monitor. I've got one sitting on a
shelf at home, which I grabbed because I never had an authentic CGA
monitor. :)

That's a good point. The question is probably moot, but I do believe the
connector coming off the CGA monitor would be universally male. Call it
an educated guess.

<mumble> years ago I built a CGA monitor. Or rather I converted an NEC
monitor that had been used with an Apple ][ to have the intensity input
(it had 3 TTL inputs as standard). I had to change the input connector,
so I mounted a male DE9 on the monitor and used a male-female lead to
link it to the CGA card.

The IBM CGA monitor (5153), and for that matter the MDA (5151) and EGA
(5154) monitors all have built-in video cables ending in a male DE9 plug
to fit the female socket on the card.
