Greetings,

I'm planning on designing an application which will use scrolling.  I
would like to build it on a TT but since it will be a while until the
TT's arrive, I would like to get a head start using an older system.
As most of you know, the 1040STe and the TT have hardware scrolling
while the other models don't.

My question is what's the difference between scrolling routines written
for an older system and a new system with hardware scrolling?  Would I have
to completely rewrite them to take advantage of the hardware or would it be
a minor modification?

If it's going to be difficult, I will either buy a 1040STe or wait for
the TT to come out.

Any help would be appreciated, thanks.
