CP/M Interlace Demo may be copied and distributed freely providing
that all files are kept intact, no fee is charged and it is not
part of a package for which a charge is made.
* OVERVIEW
CP/M Interlace Demo shows the 80 X 50 text mode feature of SG Tools
Pro VDC Screen Manager. The display is quite stable and readable
compared to other programs that use interlace without CPU
processing. I'm currently not using page flipping like 80 X 25
text mode, but that can be easily added at the loss of one
character set (I try to make everything compatible with 16K VDCs
where possible). Another modification might be to use the CPU to
control the even/odd scan lines during vertical blanking which
produces a more stable display. I use a Commodore 2002 monitor
which produces a nice display. If you use another type of monitor
please drop me a line and let me know how it looks.
* REQUIREMENTS
+ A C128 or C128D
+ At least one 1541, 1541 compatible or better disk drive
+ 80 column monitor
+ CP/M 3.0
* SG TOOLS
If you like CP/M Interlace Demo then check out SG Tools
Programmer's tool box for Turbo Pascal 2.0 or higher. SG Tools
gives you the capability to develop programs like CP/M Interlace
Demo. Turbo Pascal offers better productivity, portability and
maintainability than GEOS or C128 native mode languages. Take it
from a Commodore programmer with 12 years experience, Turbo Pascal
and SG Tools are an unbeatable combination. To get a copy of SG
