Digital Equipment Corporation (DEC)'s PDP-10, later marketed as the DECsystem-10, is a mainframe computer family [1] manufactured beginning in 1966 [2] and discontinued in 1983. [3][4][5] 1970s models and beyond were marketed under the DECsystem-10 name, especially as the TOPS-10 operating system became widely used. [a]

Digital Equipment Corporation (DEC / dɛk / ⓘ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until he was forced to resign in 1992, after the company had gone into precipitous decline.

The Digital Equipment Corporation PDP-10 (1964-1983) is one of the most influential computers in history in more ways than can be listed here. It was the foundation of the DECsystem-10 and the DECSYSTEM-20 and ran a variety of operating systems including TOPS-10, ITS, WAITS, TYMCOM-X, TENEX, and TOPS-20.

DECpc was a wide-ranging family of desktop computers, laptops, servers, and workstations sold by Digital Equipment Corporation. The vast majority in the family are based on x86 processors, although the APX 150 uses DEC's own Alpha processor. The line was DEC's first big break into the IBM PC compatible market. [1]

The project originating the PDP-6, DECsystem 10, and DECsystem 20 series of scientific, timeshared computers began in the spring of 1963, and continued with the delivery of a PDP-6 in the summer of 1964. Initially, the PDP-6 was designed to extend DEC's line of 18-bit computers by providing more perform- ance at increased price.

Digital Equipment Corporation’s PDP-10, first released in 1966 and shown here as part of the company’s DECsystem line, was one of the most important computers ever produced. It made time-share computing common, both forwarding the computer revolution and opening up a key business avenue for Hewlett-Packard.

PDP-10 offers a wide variety of on-line batch processor may run concurrently with digital-to-analog and analog-to-digital bulk storage media, including a range of real-time and time-sharing operations.

PCjs offers a variety of online machine emulators written in JavaScript. Run DOS, Windows, OS/2 and other vintage PC applications in a web browser on your desktop computer, iPhone, or iPad.

DEC TOPS-10 for the PDP-10 Having never used TOPS-10 in real life, it seemed like a good idea to get familiar with it first, using another emulator. Thankfully, The Digital Antiquarian created “ TOPS-10 in a Box ”, everything you need to run TOPS-10 on a virtual PDP-10.

The PDP-10 KI (or DEC 10), like other PDP-10 models, featured a 36-bit word length. This was significant for scientific computing and large-scale data processing, providing more precision and larger addressable memory than the more common 16-bit and 32-bit systems of the time.
