Well, I am not shipping one of mine :-)...

FWIW, the EGA card will also drive a CGA monitor if you're desparate, the
result is somewhat better than that produced by a real CGA card, of course.

I think all my EGA cards have the 'optional' RAM expansion card fitted.

At one point, I made a little adapter that plugged into the 'feature
connector' and which produced composite mono video from the RGB and sync
signals. I acutally ran an XT with that into a composite mono monitor
(with the EGA card in a CGA compatible mode) for a time.

Well, I am certainly not parting with the one I am using right now (yes,
a real IBM 5151...)

Yes, indeed. Many of the original PC parts are getting very hard to find
now. I guess because people considered them worthless :-(
