PDP-15 Simulator Configuration

Introduced in 1969, the PDP-15 was DEC's fifth (and last) 18-bit computer system. Upward compatible from the PDP-9, it included several new architectural features, including indexing, expanded memory capacity, full memory protection, and floating point. The last PDP-15 was produced in the late 1970's.
