- APLVIDEX.ASM
- -purpose to speed up console output for Apple ][ using the
- Videx 80-column card.
- -issue 1.0 14 June 1983
- -Bill McGee (613-828-9130)
- The program IOLOAD will load a new driver for the videx 80-column
- card into the text space unused when the 80-column card is installed.
- Unfortunately, this doesn't leave room for the two ZCPR2 areas
- IOBASE or NDBASE. However, I did leave room for the STKBASE, the
- CLBASE, and for EXTFCB.
- This still leaves the Apple screen pretty slow. Response times
- for writing 16k characters to the screen are
- old BIOS 19 s
- this BIOS 11 s.
- The test is IOTEST.COM.
-
- As may be seen from the source, the same SOFTWARE controls as
- assumed for the Softcard are assumed. These may be changed by
- modifying the source.
-
- This patch renders the IOBYTE for the console inoperative.
-
- The patch won't work for Apple 2E!!!
-
- For CPM60 use IOLOAD60. The source for APLVIDEX gives the relevant
- equate.
-
- Getting there!
