Sellam - When I was in school, we had a perfectly functional PDP 11/45 with VT52 terminals (about 16 or so of them). The machine was in the computer room, with all of the hardware accessible (I remember getting into strife when I wrote a program to output human readable text strings to the PTP......) One semester break, they rolled out the DEC machine, and rolled in a Prime. It was horible, and none of us actually got any useful work done for the first couple of months, while we came to grips with the new operating environment. I can't actually say that it was nicer to use than the PDP 11.... It was newer and shinier. (And it lacked the paper tape punch) In fact, I would suggest that the system was so despised by its users, that they had to put it into a cage at the back of the room, because people kept resetting it. The cage didn't work, because somebody discovered that you could still use a long broom handle to hit the reset switch..... Makes you wonder about the sanity of replacing a system that could be kept out in the open, where people didn't muck with it, because it "Just Worked" (tm), with another system that was so despised that users wanted to turn it off? Sorry, no, you won't find an emulator from anybody who enjoyed the DEC hardware..... Doug
