lol :o) well :=) i see what you mean though :)

if you allow both (either A-Z or drive numbers starting with 1) you are even 
ISO compatible :)

i'll probably add the scroll stuff myself too :) got some effect in tetris now 
thats just terribly slow without it :=P

ofcoz, no hurry :o)

okie... i'll check that when i need the rs232 stuff :)

uhmz...direction...mmmmh :O) gotta check if it makes sence to modify my 
routine :=P might be more work than rewriting it i fear :=P

ahh cool, just did last nite, didnt install yet :)

i just thought this could be a way to prevent ppl doing things that go one 
step to far already... ie, it makes more sence atm to implement the one or 
other tgi driver for some more platforms, than thinking about highlevel 3d 
functions that work on top of it :O) (mini-gl anyone? :=P).
