- AT&T 6300 BIOS CALL DEMOS
-
-
- The following programs are examples of BIOS function
- calls for the AT&T 6300 with ROM BIOS 1.21.
-
- TINYTEXT.COM delivers 80x50 lines of text
-
- NORMAL.COM delivers 80x25 lines of text
-
- LARGE.COM delivers 40x12 lines of text (for those that
- miss their old Commodore 64's)
-
- MEDIUM.COM delivers whatever's inbetween large and tiny
-
- These "programs" WILL NOT work with an IBM and will not
- work on a 6300 with ROM BIOS 1.00 and 1.10. They may appear
- to be functioning until you hit the 25th line on the screen.
- They do appear to work on any AT&T machine with DOS 3.1
- though. I haven't tried them on an IBM.
- Entering any other program will clear the interrupt and
- return the video to whatever that program is calling. You may
- be able to use the simplicity of these calls to modify the
- header of another program though.
