I am thinking about getting a HP3C scanner to tie into the animation works. There is a very good chance that this will be tied into one of the 486's until we get the second dual. Does anyone know if this scanner requires a slot for a SCSI card or does it use a port if you already have a SCSI controller installed? Also, does anyone know if this is a good scanner to use for images in the 3D environment? Thanks, Terry
