Your best place to ask is on the Yahoo "Scan Hi-end" group
Dead Link Removed
Or on the Yahoo Screen 1045 group (which I don't have a link for right now).
But as far as I know, you should be able to run it on anything that can run Mac OS8 or maybe OS 9 and use a SCSI card for connection. There might also be PC software which could open up really large file sizes (beyond the 2 to 4 GB limit). If it has an ADB dongle, then about the newest machine is a Blue/White Mac G3 which you can hop up to 1GB ram and 1Ghz processor with a several GB hard drive.
As far as the monitor for that machine goes, just buy a Mac DB15 to high density DB15 adapter like this one:
