- This library contains 3 VERY simple programs for the IBM Enhanced Graphics
- Adaptor: 43.com, 25.com and pallette.com (and source for pallette). There
- is also a short batchfile which I use for making .com files.
-
- 43 and 25 assume that the EGA is being used in 350 line mode, either as
- an IBM Mono emulator, or with an IBM Enhanced Color Display in Enhanced Color
- Mode (ie: 350 visible scan lines rather than 200). 43.com will put the EGA
- into 43 line mode (with a cursor!) while 25.com will put it back into 25 line
- mode. Some programs will work OK with 43 line mode, some won't. The only
- trick is that the EGA fails to live up to my (skimpy) documentation when it
- is switched to 43 line mode, and does NOT reset the cursor start register as
- it should - so 43.com also sets the cursor start. These were created with
- debug, so there is no source.
-
- Pallette.com is just a quickie to let you play with the color pallette with
- the Enhanced Display (5154). Put something colorful on the screen, then
- invoke the program. Press '0'..'9' ':'..'?' to select pallette registers
- 0..15, then use 'r', 'g', 'b' to vary the amount of each color in the mix
- (cycles thru black, dim, normal, bright). Any other key should take
- you back to DOS. The new pallette will be used until you use "mode color"
- or the like. This has hardly been used, so no guarantees. Source is included.
- Let me know if you make it more useful.
-
- Makecom.bat is a batch file I often use to create .com files from .asm
- files. Use it thus:
- makecom sourcename

- Good Luck
