The PDP-15 was the fifth and last of the 18-bit minicomputers produced by Digital Equipment Corporation. The PDP-1 was first delivered in December 1959[3]: P.4  and the first PDP-15 was delivered in February 1970.[4] More than 400 of these successors to the PDP-9 (and 9/L) were ordered within the first eight months.[3]: p.16 

In addition to operating systems, the PDP-15 has compilers for Fortran[5] and ALGOL.[6]
