PDP-7

The DEC PDP-7 is a minicomputer produced by Digital Equipment Corporation. Introduced in 1965, the first to use their Flip Chip® technology, with a cost of only $72,000 USD, it was cheap but powerful. The PDP-7 was the third of Digital's 18-bit machines, with essentially the same instruction set architecture as the PDP-4 and the PDP-9. It was the first wire-wrapped PDP.

There are a few remaining PDP-7 still in operable condition, and an interesting restoration project in Oslo, Norway.
