[avr-gcc-list] Stepper motor driving?

Hi, I'm new to AVR's and this list, so please be patient with me!

I'm considering using a stepper motor to drive a camera panoramic head,
hopefully to enable me to select on a keypad the number of images in 360
degrees I want, and the delay before images start being taken (so I can hide
behind a tree and not be in the picture!).

I already have a 8 wire stepper motor with a nice reduction gearbox fitted
and have bought an av90s2313 based board ('Microbot'). I've also been give a
av90s1220 that I'm going to use for a prototype board. I've a _little_
experience in Z80 programming (going back about 15 years!) and some 'C'
experience. I anticipate a steepish learning curve for learning to progarm
the AVR chips.

My question is: Am I on a loser with the above AVRs, or do I need something
a bit more 'heavyweight'? Also, does anyone know of a similar project that I
can crib from?

I would be grateful for any info on using stepper motors - googling initially
looked productive, but the most useful looking links proved to be dead!
