Help with peripheral selection

I'm a new GRASS user with GRASS4.0 running on a Sun SPARC10. I'd like to
be able to scan in a map, and use it as a base layer on which to overlay
digitized data and data from other sources, registering all layers using
lat-long. Can anyone help with hardware configuration, or vendor suggestions
?? Also, I'd like to be able to play through several of the above-type
images in time sequence - like a movie. Any ideas about appropriate packages?

Thanks'
