The PDP-14 was designed to process Boolean equations, usually expressed as “ladder diagrams” and as such had a programmable read-only program memory. Programs were developed using a PDP-8 then tested using a direct connection to the PDP-14. The PDP-14 was put into a check out mode where instructions were provided by the PDP-8.

The PDP-11 is booted from a dual-ported RP06 disk drive (or alternatively from an 8" floppy disk drive or DECtape), and then commands can be given to the PDP-11 to start the main processor, which is typically booted from the same RP06 disk drive as the PDP-11. The PDP-11 performs watchdog functions once the main processor is running.
An open PDP-8/E with its logic modules behind the front panel and one dual TU56 DECtape drive at the top A "Straight-8" running at the Stuttgart Computer Museum. The earliest PDP-8 model, informally known as a "Straight-8", was introduced on 22 March 1965 priced at $18,500 [3] (equivalent to about $178,900 in 2023 [4]).
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-12 (Programmed Data Processor) is a computer that was created by Digital Equipment Corporation (DEC) in 1969 and marketed specifically for science and engineering. [1] It is the third in the LINC family and its main uses were for applications in chemistry, applied psychology, patient monitoring and industrial testing. [ 2 ]
RSX-11 is a discontinued family of multi-user real-time operating systems for PDP-11 computers created by Digital Equipment Corporation.In widespread use through the late 1970s and early 1980s, RSX-11 was influential in the development of later operating systems such as VMS and Windows NT.
