Hello all;
I'm dusting off some of my disk images and the Kegs emulator to give a
nostalgic Apple // demonstration at our computer club.
I have a problem that I can't remember the solution to for the life of
me. I have a menu "launcher" in 80 column mode. I have a selection
of "Mathland" (ie. Nibble Sept 86 page 70) programs. When I select
one, the Kegs emulator screen just becomes a static pattern of
multicolored pixels instead of the geometric plot that its supposed to
be. The mathland programs use HGR mode.
Is there some specific settings that I'm supposed to use to get these
to display properly? I'm certain I'm just forgetting something silly,
its been almost 10 years since I got rid of my Apple // hardware and I
only use the emulators when nostalgia raises its head.
Thanks in advance.
if your multi colored screen is showing more than the normal six
colors of black, white, orange, blue, violet and green, i.e you see
yellow, red, etc. ... then it is possible the double hi-res screen is
engaged.
Are your Mathland programs, applesoft programs?
Use ? CHR$(21); at the beginning of the program to disengage 80
columns

Yes, they are 4 line applesoft programs and they start off with HGR;
