Yes, if I remember correctly, there are two jumper areas on the original
EGA card that need to be moved. I bought an EGA card years ago from a
second hand dealer and it came with the techref suppliment, which I
still have. Thanks for reminding me to be careful and doublecheck when
I get going on that AT.
I was probably one of the few people who ran EGA-Monochrome on an XT,
back when an XT was all I could afford. EGA-Monochrome was very well
supported in a few essential apps like Microsoft Word for DOS, and it
also gave a MUCH better video resolution for Windows 3.0 on a 9-pin mono
monitor than a Hercules card. Back in the days when I was too cheap to
buy an expensive EGA monitor and ran Windows on an 8088 machine...
Running EGA-monochrome kept me from wasting my time playing games, since
there was none, nadda, no support at all for gameplaying type graphics
on EGA-mono.
On this topic,
I recently located an original IBM Monochrome
monitor, so for me it's now just a matter of pulling out the EGA
Techref and jumpering the IBM EGA card in my AT for EGA monochrome
and plugging the
One thing a lot of people forget : There's a jumper on the board near
the DE9 connector which selects where pin 2 of said DE9 goes (LSB of
one of the colours for an EGA monitor, ground for an MDA or CGA
monitor). If you set that to the EGA position and then connect an MDA
(or for that matter CGA) monitor, you're shorting an output line to
ground via the monitor cable. It probably won't do any harm, but why
risk it...
