- OVERVIEW
- The Hercules Graphic Card is a pretty good/cheap Videoadapter. If
- you try calculating, you'll work out that 90x43 characters can be
- displayed with a 8x8 pixel matrix on the 720x348 pixel screen.
- Cause the original EGA uses the 8x8 pixel matrix too, the display-
- ed text looks still very good.
-
- My intention to write this program have been monitors, which can
- display much more than 25 lines of text. Since I don't have the
- money to buy such a beast, I preferred the software solution.
-
- This program emulates parts of an EGA. This is detection of video
- adaptor and switching between 25/43 lines. But the most important
- thing is: this program simulates the 43-line mode. This is done
- by continuosly copying the characters from text to graphic screen.
- The problem is, this can only be done at great expense of com-
- puting speed. Since the standard equipment is an AT 286 compatible
- computer with at least 12 MHz, there is still enough power.

- You find more documentation in 43.doc, hmode.doc, egafont.doc.
