I've got a couple of 68K Macs capable of running A/UX in my UK flat but they're both having HD problems, i.e. the one that came with them is borked and the formatting utility that comes on the A/UX install floppy won't recognize any new ones - actually, come to think of it, it might just be the SE/30 that's totally broken, need to try my 2 GB external drive with the Quadra. I think A/UX even does TCP/IP and is pretty nifty to use apparently, like Unix with System 7 bolted on (thinking of trying to get a VNC server running on them too for remote access).

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 I know there was a Datakit adapter for the 3B2 and 3B20, did the 3B1 have such a thing? -brian
