[net.micro.pc] CGA adaptors with TTL output?

edw@ihopa.UUCP (EDWindes) (10/29/86)

A friend recently bought a Leading Edge Model D computer, and I became
  her (unpaid) computer consultant.  She is very happy with it, but
  would like to run programs written for the CGA.  Unfortunately, her
  student budget was taxed nearly to its limits, and can't accomidate
  a color monitor.
PHEWW!  OK HERE'S THE QUESTION:

Is there such a thing as a CGA board that spits out TTL signals compatible
  with a monochrome monitor?  If so which ones?  Please mail responses.

thanks.					ed windes (...ihnp4!ihopa!edw)

There are a number of video boards that will emulate CGA on a mono screen.
We have used ATI Graphics Solution quite successfully here. It does a lot
more than emulate CGA. It will drive TTL mono, RGB, Composite, and also
emulate a Herc Graphics card. Good hunting... Oh... they also have out
an EGA solution that does all the above plus EGA...

Actually, the IBM CGA works fine with a monochrome monitor.  You just
can't use the IBM monochrome monitor.  There are others that can be
made to work with just a special cable.

I only tried one and it performed miserably.  It was a Paradise card.
It was brutally slow and caused all manner of flicker/breakup problems.
I beat a hasty retreat.
