in the german magazine 'ST magazine' dated 5/89 there is a discription of
a extremely simple and low-cost (2 dollar) change discriped, that gives
the atari a resolution of 840*568 points (on a normal atari monochrome
monitor sm124/125)
programs like 1st word plus, calamus or gfa basic 3.04 seem to run perfectly
using this increased graphics area.
Besides the hardware change (2 diodes, 2 resistors, 1 transistor,
1 capicitor, and one switch) the only thing needed is a small program to
tell GEM about the bigger area.
I didn't test it yet. I will not test it, until someone else can tell me
if uniterm will use this enlarged area if uniterm is in graphics mode.
