> I don't know my PDP stuff well.. the 11/45 is from around the early 70s right?
1972 I think. It's a very nice machine, all TTL (over 1000 ICs in CPU, MMU and floating point processor). I suppose the 11/70 is even more fun (with 22 bit addressing, etc) but the 11/45 is one of my all-time favourites. -tony
