It'd be a pretty nifty addition to a collection, I'd love a really old school Unix machine. If memory serves, the UNIX dialect that they run is SysV release 2. It's a fairly complete SysV implementation, with a nice, low-overhead GUI called "UA", for User Agent. There is no networking, but there's a (rare) Ethernet card for the machine, which was shipped with an IP stack written by Wollongong. The IP stack ran in short spurts between crashes, but you could use it to get stuff on or off the machine. Well there's always Kermit and UUCP - and one could always plug a few serial ports into a DECserver or something to get "networking" into the device :) I ran UUCP on mine, years ago. It worked well. The internal modem is 1200 baud. (which was great at the time!) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
