[comp.sys.ibm.pc] Strange Herc card, and compatibility probs.

msmith@topaz.rutgers.edu (Mark Robert Smith) (03/28/88)

I have bought a used clone, and it comes with a "MGP CARD" mono
adapter with parallel printer port.  Curiously, the manual says that
the board is Herc compatible, and provides 720Hx348V mono graphics.
It doesn't work with Dutchie 2.71, or AN, or a lot of my other
programs, and SIMCGA40 doesn't work.  I get the problem of having only
pure white characters displayed.
Can anybody help?  Do I gotta buy another card?

Oh, I forgot.  The manual doesn't have the address or name of the
manufacturer in it, and I didn't get anything else on the card.

I have one of these (from AMT - may they rot in ...) and it works wonderfully
in herc mode; simcga3? works quite well on it too!  Are you perchance
expecting to see "grey" scales or different brightnesses for your "color"
characters?  The Hercules only gives you ONE bit plane which means either
a dot is ON or it is OFF - no other brightness levels are avaliable.

Turbo pascal 4.0, Turbo C 1.5, MSC W/3rd party herc support, and my own
herc graphics routines all work well on the MGP (Mono Graphics Printer) card.

The only problem I've found is that under a few circumstances, if you
print the string "_^H<Cursor addressing sequence>, the cursor is not displayed
correctly until another char is displayed on the screen...  Not really
a problem cuz it doesn't happen all the time, but strange.

I'm not looking for gray, but I am looking for all of the stuff I'm
supposed to see showing up on the screen.  SIMCGA40 leaves only the
pure white chars on the screen, as does the Herc card without any TSR.
I think I'm just gonna buy an EGA Wonder.
