I have a Hercules card that works exactly like an IBM-PC CGA card.
I see a lot about different hercules cards and their capabilities, and
am somewhat confused as to the different models. I think my card
has better graphics abilities than the CGA, but I don't know how to access
them (I never got a manual with the card.)
If anybody could tell me what the different hercules models are, and
what they can do, it would be greatly appreciated.
Thanks,

Its normal mode of operation is identical to its IBM counterpart. It has an additional mode of operation allowing for 720x348 monochrome graphics. Unfortunately, in this mode, character output is a pain, and without other software (ie. SIMCGA) programs written for the CGA will not run on it (different resolution and memory mapping). The Hercules CGA (what I presume you have) is a direct replacement for the IBM CGA. It fits in a short slot and contains a parallel printer adapter (which the IBM CGA does not). I don't believe that it has any additional operating modes. The newest Hercules board seems to be a Hercules graphics board that will also allow for easy character output, loadable character sets, and direct communication with aliens from Mars (well, maybe not, but the advertising might lead you to believe it does). I don't know much more about it. Since the Hercules board has become a "standard," there are several "clones" on the market. It is hard to say what they do and do not do. Alan Groupe
