PDP-7

The DEC PDP-7 was a minicomputer produced by Digital Equipment Corporation as part of the PDP series. Introduced in 1965, it was the first to use their Flip-Chip technology. With a cost of only US$72,000, it was cheap but powerful by the standards of the time. 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. The computer had a memory cycle time of 1.75 µs and add time of 4 µs. I/O included a keyboard, printer, paper-tape and dual transport DECtape drives (type 555). The standard memory capacity was 4K words (9 kB) but expandable up to 64K words (144 kB).
