Flip to Kermit-20
Digital Equipment Corporation's 36-bit PDP-10 was, arguably, the birthplace (together with its sibling, the DECSYSTEM-20) of both the Internet and the Open Source movement, and without argument, the source of many of the most influential software applications, including EMACS, TEX, ISPELL (the first spell checker), MACSYMA, SCRIBE, numerous LISP dialects, MM and other pioneering email clients, and Kermit.
The PDP-10 was the successor to the PDP-6, which appeared in 1964. PDP-10s came in four models: KA10, KI10, KL10, KS10. The primary operating system for the DECsystem-10 was DEC's TOPS-10 ("Timesharing Total Operating System-10"). The typical PDP-10 installation included multiple full-size cabinets for CPU, memory, controllers, networking front ends, and magnetic tape, plus washing-machine sized disk drives, line printers, and so on, requiring a large machine room with serious air conditioning and a great deal of 3-phase power; the electrical bill alone ran into the thousands of dollars per month, ditto for hardware maintenance. This was typical of any mainframe of the era.
Other PDP-10 operating systems included MIT's ITS, Stanford's WAITS, Tymshare's TYMCOM-X, the version of TENEX that Xerox PARC ran on their MAXC PDP-10 clone (more or less equivalent to a KA-10 with BBN pager), and maybe some others. The PDP-10 line was canceled by DEC in 1983 and the machine gradually faded from view in the ensuing years. Manufacturing ceased in 1988. Some machines or clones remained operational through the 1990s (and a handful even to this day as museum pieces), and then in 2001 a renaissance of PDP-10 culture began with the release of several Unix- and/or Windows-based PDP-10 emulators (see Links section).
The distinguishing feature of PDP-10 is its rich instruction set and powerful repertoire of system services. This combination made the PDP-10 more fun to program than any other computer before or since (except the DECsystem-20!), and spawned a generation of prolific programmers ranging from Richard Stallman to Bill Gates.
