** ITS ( MIT's Incompatible Timesharing System for the DEC PDP-6 and PDP-10 )

Greenblatt was convinced by Ed Fredkin that time-sharing systems could be more beneficial, so he set out, along with Nelson, to write a new time-sharing system called ITS, or Incompatible Time-sharing System, initially for the PDP-6, and later the PDP-10.

Greenblatt, along with Tom Knight and Stewart Nelson, co-wrote the Incompatible Timesharing System, a highly influential timesharing operating system for the PDP-6 and PDP-10 used at MIT.

The TOPS-10 System ( Timesharing / Total OPerating System ) was a computer operating system from Digital Equipment Corporation ( DEC ) for the PDP-10 ( or DECsystem-10 ) mainframe computer launched in 1967.

It was initially developed in 1971 on the PDP-10 computer under the Incompatible Timesharing System.

The clients ran on Imlacs which had 50 kbit / s serial connections allowing them to communicate with PDP-10 computers running MIT's Incompatible Timesharing System ( ITS ).

Originally written to run on a Burroughs Corporation B6700 Main frame in Fortran IV, subsequently rewritten in SMALL and ported to a DEC PDP-10 Architecture ( on the Operating System TOPS-10 ) and IBM S360 Architecture ( on the Operating System VM / CMS ).

The PDP-10 was as much a success as the PDP-6 was a failure ; during its lifetime about 700 mainframe PDP-10s were sold before production ended in 1984.

Don Daglow wrote an enhanced version of the program called Ecala on a PDP-10 mainframe computer at Pomona College in 1973 before writing what was possibly the second or third computer role-playing game, Dungeon ( 1975 ) ( The first was probably " dnd ", written on and for the PLATO system in 1974, and the second may have been Moria, written in 1975 ).

The PDP-10 was a mainframe computer family manufactured by Digital Equipment Corporation ( DEC ) from the late 1960s on ; the name stands for " Programmed Data Processor model 10 ".

The DECSYSTEM-20 was a 36-bit Digital Equipment Corporation PDP-10 mainframe computer running the TOPS-20 operating system.

The TOPS-20 operating system by Digital Equipment Corporation ( DEC ) was the second proprietary OS for the PDP-10 mainframe computer.

By early March, Paul Allen, Bill Gates, and Monte Davidoff, another Harvard student, had created a BASIC interpreter that worked under simulation on a PDP-10 mainframe computer at Harvard.

Microsoft's software development was done on a DEC PDP-10 mainframe computer system.

WAITS was a heavily-modified variant of Digital Equipment Corporation's Monitor operating system ( later renamed to, and better known as TOPS-10 ) for the PDP-6 and PDP-10 mainframe computers, used at the Stanford Artificial Intelligence Laboratory ( SAIL ) up until 1990 ; the mainframe computer it ran on also went by the name of " SAIL ".

Colossal Cave was a year earlier, but on a mainframe, the PDP-10.

* Don Daglow programs Star Trek on a PDP-10 mainframe computer at Pomona College.

Lunar Lander ( also known as Moonlander ) is an early computer game that runs on the DEC GT40 graphics terminal ( typically downloaded from a PDP-10 mainframe computer ).

The most popular type of MMOG, and the sub-genre that pioneered the category, is the massively multiplayer online role playing game ( MMORPG ), which descended from university mainframe computer MUD and adventure games such as Rogue and Dungeon on the PDP-10.

For example, the Data General Nova minicomputer, and the Texas Instruments TMS9900 and National Semiconductor IMP-16 microcomputers used 16 bit words, and there were many 36-bit mainframe computers ( e. g., PDP-10 ) which used 18-bit word addressing, not byte addressing, giving an address space of 2 < sup > 18 </ sup > 36-bit words, approximately 1 megabyte of storage.

Clem is one of the first " computer hackers " mentioned in pop culture, and his dialog with the fair's computer includes messages found in the DEC PDP-10, a popular mainframe computer at the time.

The first computer game to implement line of sight graphics was Dungeon, which was played on a PDP-10 mainframe computer ( 1975 ).

Other versions of Runoff were developed for various computer systems including Digital Equipment Corporation's PDP-11 minicomputer systems running RT-11, RSTS / E, RSX on Digital's PDP-10 and for OpenVMS on VAX minicomputers, as well as Sperry Unisys Univac 90 / 60 mainframe using the EDT text editor under the VS / 9 operating system.

* One of the first sim games, Killer Shrews, based on the cult movie The Killer Shrews, is programmed on the PDP-10 mainframe at Claremont Graduate University by Don Daglow.

Dungeon was one of the earliest role-playing video games, running on PDP-10 mainframe computers manufactured by Digital Equipment Corporation.

The Jupiter project was to be a successor to Digital Equipment Corporation ( DEC )' s PDP-10 mainframe computer model.

Star Trek was a text-based mainframe computer game written by Don Daglow on a PDP-10 timesharing computer at Pomona College in 1972, and upgraded periodically through 1974, including contributions by Jonathan Osser.

Baseball was a baseball sports game that was created on a PDP-10 mainframe computer at Pomona College in 1971 by student Don Daglow.

The DECsystem ( or DECSYSTEM ) name was also used for later models of the PDP-10 mainframe, namely the DECsystem-10 and DECSYSTEM-20 series.

While the first such systems were purchased from DEC, when DEC abandoned the PDP-10 architecture in favor of the VAX, CompuServe and other PDP-10 customers began purchasing plug compatible computers from Systems Concepts.

The PDP-10 was eventually eclipsed by the VAX superminicomputer machines ( descendants of the PDP-11 ) when DEC recognized that the PDP-10 and VAX product lines were competing with each other and decided to concentrate its software development effort on the more profitable VAX.

The PDP-10 version of Interlisp became Interlisp-10 ; BBN had an internal project to build Interlisp-Jericho and there was a 1982 port to Berkeley Unix on the VAX by Stanford University, ISI and Xerox PARC, called Interlisp-VAX.

* All constants are full word for the machine being used, e. g. on a 16-bit machine such as the PDP-11, a constant is 16 bits ; on a VAX computer, constants are 32 bits, and on a PDP-10, a constant is 36 bits.

This project was cancelled in 1983, as the PDP-10 was increasingly eclipsed by the VAX supermini machines ( descendants of the PDP-11 ).

DEC recognized then that the PDP-10 and VAX product lines were competing with each other and decided to concentrate its software development effort on the more profitable VAX.

RADIX-50's 40-character repertoire ( 050 in octal ) can encode 6 characters plus 4 additional bits into one 36-bit word ( PDP-6, PDP-10 / DECsystem-10, DECSYSTEM-20 ); 3 characters plus 2 additional bits into one 18-bit word ( PDP-9, PDP-15 ); or 3 characters in one 16-bit word ( PDP-11, VAX ).
