Questions on a CNC Controller (AhHa) I am rebuilding

(These are condensed versions of questions posted on the AhHa board.
No response there. Perhaps someone here will have some wisdom to
offer)

QUESTION #1. Any benefit/Plans for greater than 640x480 on the
controller software

I'm building my CNC controller and computer into a small rack in
which I already have a 640x480 LCD Monitor installed.

I'm wondering if any of you know if there are any plans for a version
of AhHa that would use more than 640x480. If not, I'll proceed to
mount this display into the chassis.

QUESTION #2.Is there any reason to use a CPU Faster than PII-333MHZ,
128MB RAM?

Since I'm building my CNC controller into a small rack. I'd rather
not
have to rebuild it in the forseeable future.

Are any of you aware of any circumstances where an Intel Pentium II-
333Mhz with 128Megs of RAM would not be sufficient? I'm driving a
Sherline Mill & Lathe.

I don't know how much caching AhHa 4.0 does so I don't know if the
extra RAM would be used or if it is a waste.

Thanks for any feedback.
