If you used Double-High-Resolution, you would have more colours automatically.
Peek/Poke won't get you any more colours on the screen. More colours can be
accomplished by mixing colours, but this is more complex than a few
peeks/pokes.

If you have a Grappler parallel printer interface, then the card has graphic
screen dump software, in ROM, eg.
PR#1
control-I G <return>
will dump page 1 to the printer, unrotated,
control-I G D
will dump page 1 to the printer, unrotated, double size.
Other modifiers include I for Inverse, R for Rotate, E for Emphasized, 2 for
Page 2. If this is indeed the card you have, you should read the manual.
