What do you do with 256k Wang

Okay, I own a computer so of course to everyone who doesn't I'm some kind of expert (not). So the other day this guy brings me this 256k Wang, wants me to set it up for him. Set up to do what? Alright maybe I may have some old DOS stuff a wordprocessor, spreadsheet, hell maybe I even got a pong game still laying around. My problem is how do I write to this thing? Its got one of those old floppy drives with the lever and all (never used them I was running a Mac before IBM saw the light). The hard drive is with connections for a network possibly? Probably a mainframe Yuk. Anybody ever own one of these things? Can anything be salvaged? Is this just an overgrown typewriter? How am I going to write to this thing without destroying my computer? Help Help Help... Here's some numbers: cpu 256kb, two PMO30-b 128k Memory expansion, PMO08 c.g.I (monitor controller?), pm02/022-b Winchester controller,Seagate HD, and of course the standard Wang kb and monitor (RGB I think they called them you know green just green). Everything works even has some old data base software still on it. FrednLenny(a)compuage.com
