It'd be a pretty nifty addition to a collection, I'd love a really old school Unix machine. I'd not call the 3B1 "old school", but they're lots of fun. I've had a bunch of them over the years, including used one as my main desktop machine for a while in the late 1980s. I also worked at a store that sold and serviced them. 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. I have two 3B1s now. I like them a lot. If you really want "old school UNIX", find a 3B2. Or REALLY old school, v7 on a PDP-11. -Dave -- Dave McGuire, AK4HZ New Kensington, PA Hello! Yikes! I knew an AT&T 7300 machine once. It was an interesting machine. I almost ended up with it when the store I was (temporarily) associated with here in Queens was forced out of business by its <DELETED!> of a landlord. I also saw a 3B family machine at that same show where we met. The owners couldn't get the thing to work, but the terminal ran rather well. Now why is there an entire van of Yetis and four Cybermen and six Daleks watching you? ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."
