KEGS? Even a real IIgs doesn't do the same thing as a real II Plus.

I saved the RAINBOW program on a 5.25" disk so I wouldn't have to type it
again. I loaded it on the IIgs. The results were... we shall say...
interesting.

On Fast speed (that's 2.8 MHz for me) there was quite a bit of screen
flickering. On normal speed, the flickering was less so, and was isolated
the right side of the screen.
