Is An Old Honeywell Tablet Useful For Anything?

I picked up a couple Honeywell Thor VM1 industrial computers 2nd-hand. After a couple weeks of screwing around with them, the only thing I can get to work is Doom! I haven't been able to get a real OS onto it or run much other software successfully. These seem to be one of those proprietary overpriced gadgets designed to go in a landfill as soon as they're past their original use. If anyone has suggestions or other ideas for it, I'm all ears, but first I need a way to get an operating system on there!
