PDP-1 PDP-6 PDP-7 PDP-8/e PDP-11/40 PDP-12 PDP-15 (partial) PDP-15 graphics terminal with light pen and digitizing tablet. Programmed Data Processor (PDP), referred to by some customers, media and authors as "Programmable Data Processor," [1] [2] [3] is a term used by the Digital Equipment Corporation from 1957 to 1990 for several lines of minicomputers.
A PDP-9 on display at ACONIT in Grenoble, France. The PDP-9, the fourth of the five 18-bit minicomputers produced by Digital Equipment Corporation, was introduced in 1966. [1]: P.10 A total of 445 PDP-9 systems were produced, [2] of which 40 were the compact, low-cost PDP-9/L units. [3]
The PDP-7 was introduced in December 1964, and about 120 were eventually produced. [25] An upgrade to the Flip Chip led to the R series, which in turn led to the PDP-7A in 1965. [26] The PDP-7 is most famous as the machine for which the Unix operating system was originally written. [27] Unix ran only on DEC systems until the Interdata 8/32. [28]
The 11/34 supports up to 256 kB of Unibus memory. The PDP–11/34a (1978) [15] supports a fast floating-point option, and the 11/34c (same year) supported a cache memory option. PDP–11/60 – 1977. [15] A PDP–11 with user-writable microcontrol store; this was designed by another team led by Jim O'Loughlin. PDP–11/44 – 1979. [15]
The PDP-11/73 [1] [2] (strictly speaking, the MicroPDP-11/73) was the third generation of the PDP-11 series of 16-bit minicomputers produced by Digital Equipment Corporation to use LSI processors. Introduced in 1983, this system used the DEC J-11 chip set and the Q-Bus , with a clock speed of 15.2 MHz.
The PDP-10 assembly language instructions LDB and DPB (load/deposit byte) live on as functions in the programming language Common Lisp. See the "References" section on the LISP article. The 36-bit word size of the PDP-6 and PDP-10 was influenced by the programming convenience of having 2 LISP pointers, each 18 bits, in one word.

1956 Babe Bee 049 (Cat#350 - manufactured Nov 1956 – Jan 1996) The classic Babe Bee was the first engine Cox produced with an extruded machined anodized bar stock aluminum crankcase. This crankcase was machine made and was much cheaper and faster to make than the cast aluminum crankcase of the earlier models.
