Gary Kildall, who developed CP/M and MP/M, based much of the design of its file structure and command processor on operating systems from Digital Equipment, such as RSTS/E for the PDP-11. Besides accessing files on a floppy disk , the PIP command in CP/M could also transfer data to and from the following "special files":
A more complex MACRO-10 example program, which renders one version of the 99 Bottles of Beer song, may be examined at the "99 Bottles of Beer" web site. [2] For larger bodies of code, much of the MACRO-10 code for the TOPS-10 and TOPS-20 systems is available in the Trailing Edge PDP-10 tape archives. [3]
TOPS-10 supported shared memory and allowed the development of one of the first true multiplayer computer games. The game, called DECWAR, [2] was a text-oriented Star Trek-type game. Users at terminals typed in commands and fought each other in real time. TOPS-10 was also the home of the original Multi User Dungeon, MUD, the forerunner to today ...
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.
FOCAL was later implemented on the PDP-7, PDP-9, PDP-10, PDP-11, PDP-12, PDP-5 and LINC-8. The FOCAL manual showed how to add commands to the FOCAL parser, so many sites added specialized commands for operating custom hardware. The Digital Equipment Computer Users' Society collected many patches and enhancements for FOCAL. There were even major ...
This compromise impacted system sales; by this point TENEX was the most popular customer-written PDP-10 operating systems, but it would not run on the new, faster KI-10s. To correct this problem, the DEC PDP-10 sales manager purchased the rights to TENEX from BBN and set up a project to port it to the new machine. At around this time Murphy ...

It is the successor to PAL-11 (Program Assembler Loader), an earlier version of the PDP-11 assembly language without macro facilities. MACRO-11 is supported on all DEC PDP-11 operating systems. PDP-11 Unix systems also include an assembler (called "as"), structurally similar to MACRO-11, but with different syntax and fewer features.
