Do you think that PDP-11 computers can only work in a conditioned rooms? And that they are not portable. Well, you are almost right. But in the Soviet Union everythink was possible. They even had a portable PDP-11! It was called Elektronika MK-90.
Well, it is a bit limited machine: it has a LSI-11-compatible CPU and it run an ancient version of the BASIC interpreter. No UNIX can be used here because of a very limited memory (16 kB) and storage (up to two MPO-10 battery-backed memory moduli of 16 kB each).
Anyway, it is a cool little computer with graphical capabilities and other nice features. Ant it runs on four AA batteries.
So I finally have my very own PDP-11!
