I'm using both a G4 tower w/ 500mhz and a newer Powerbook @1.67Ghz. I'm
scanning Agfa Optima 100 color negatives 120 size (6x9). I'm setting
the scanner at 2400 dpi on the original neg size. The tower is
stumbleing and taking way too long. I stopped it after 54min and it
said it would be another 94 min! The laptop did it in 28 minutes. Does
that sound reasonable? Does anybody have any ideas what might be going
on with the older tower?

There would be several reasons the older computer is taking so long.

The first you said, it is a 500 Mhz processor, which is slow by today's
standards.

You probably don't have much RAM in the older computer and the USB is most
likely USB 1.0 or 1.1 which is only 12 Megabits per second in the best of
conditions.

Also the hard drive in that computer is likely slower and smaller (5400 RPM
vs. 7200 RPM).

In short you need to upgrade your desktop computer to a newer and faster
computer.
 
My guess is that you have ICE enabled. That will choke a 500 mhz machine!
Deactivate ICE plus turn off grain reduction, descreening, etc., and you
should see the times for both machines drop dramatically.

We have used a V700 with a G4 850 (1.5G RAM) and had no problems.
Another poster is correct that USB is 1.1, get a firewire cord and
things will speed up (oops does the 4990 support firewire?). RAM helps
too. You are probably getting 100mb image at 2400 ppi (200mb at 16bit)
If you don't have at least a gig of memory you are choking the
computer, again ours is fine with 1.5g.
I have a windows machine with a gig that I have done 4x5 at 2000 ppi
in about 10 minutes. The transparancy had been stored well and didn't
need ICE. ICE is a hog but if there is alot of dust it works miracles.
I do a lot of low res scans for folks converting slide show to digital,
ICE works great there but it does double the scanning time, it also
cuts the sharpness slightly, but dust vs sharpness it is your call.

good luck
