WTB: Pro380, VAXstation

Torquil> Since it seems no one has any PDP-11 stuff, does anyone have Torquil> a Pro380? I'd really just like to learn more about the Torquil> PDP-11 and this seems like the easiest route. (By the way, my Pro380 isn't for sale... I missed that part of the question.) As for a Pro being the easiest route, I wouldn't say so. The bus architecture is completely unrelated to that of any other PDP11, and ugly/messy/baroque/bogus at that. There is NO DMA. The Ethernet card uses the worst Ethernet chip I know. Off the shelf software for a Pro is P/OS, a mangled version of RSX. I believe there's also an RT11 that works on it. At one time DEC created a Unix for it, then canceled that a week before the product was supposed to ship, and replaced it by a different unrelated Unix instead. Typical DEC messed up management... No other OS runs (stock) on a Pro, though I have modified RSTS to do that. If you have a choice, a PDP11/73 would be a far better choice, or one of the later ones in that small packaging. Or an 11/23, though those are rather slow. paul
