This was in turn inspired by an older program with the same name running on TOPS-20.

The original Interim Mail Access Protocol was implemented as a Xerox Lisp machine client and a TOPS-20 server.

TOPS-10 was running on the Mars by the summer of 1984, and TOPS-20 by early fall.

In particular, all ARPAnet TOPS-20 systems had an I / O bus because the AN20 IMP interface was an I / O bus device.

The first operating system that took advantage of the Model B's capabilities was TOPS-20 release 3, and user mode extended addressing was offered in TOPS-20 release 4.

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

Most ( but not all ) machines sold to run TOPS-10 were painted " Blasi Blue ", whereas most TOPS-20 machines were painted " Terracotta " ( often mistakenly called " Chinese Red " or orange ; the actual name of the color on the paint cans was Terracotta ).

Digital never made a PDP-20, although the term was sometimes used for a PDP-10 running TOPS-20 ( officially known as a DECSYSTEM-20 ).

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

TOPS-20 is almost entirely unrelated to the similarly named TOPS-10, but it was shipped with the PA1050 TOPS-10 Monitor Calls emulation facility which allowed most, but not all, TOPS-10 executables to run unchanged.

Ultimately DEC picked TOPS-20 as the name of the operating system, and it was as TOPS-20 that it was marketed.

As late as the mid 1980s, PIP was still in common use on TOPS-10, TOPS-20 and PDP-11 systems.

During that time, he wrote the infamous RFC 748, the only document specifically marked in the RFC index with note date of issue ; and a series of Telnet implementations for the Incompatible Timesharing System, WAITS, and TOPS-20 operating systems whose escape behavior was playfully immortalized by Guy Steele in the April 1984 Communications of the ACM as The Telnet Song.

It had its roots in the IAS, TOPS-20, and RT-11 operating systems and was implemented as a standard across most of Digital's operating systems, notably RSX-11, but took its most powerful form in the OpenVMS operating system.

Another early implementation of versioning was in TENEX, which became TOPS-20.

It was first used in this context with regard to the TENEX operating system, later distributed under the name TOPS-20 in the 1960s and early 1970s.

The term was adopted by Unix users in the 1980s, due to the movement of operating system developers and users from TENEX / TOPS-20 to Unix.

Later on, those systems running TOPS-20 ( on the KL10 PDP-10 processors ) were labeled DECSYSTEM-20 ( the block capitals being the result of a lawsuit brought against DEC by Singer, which once made a computer called " system-10 ").

DEC attempted to convince TOPS-20 users to convert to VMS, but instead, by the late 1980s, most of the TOPS-20 users had migrated to Unix.

Digital Equipment Corporation developed many operating systems for its various computer lines, including TOPS-10 and TOPS-20 time sharing systems for the 36-bit PDP-10 class systems.

In 1978, there were half a dozen different operating systems for the PDP-10: ITS ( MIT ), WAITS ( Stanford ), TOPS-10 ( DEC ), CMU TOPS-10 ( Carnegie Mellon ), TENEX ( BBN ), and TOPS-20 ( DEC, based on TENEX ).

Both could run either TOPS-10 or TOPS-20 microcode and thus the corresponding operating system.

Tymshare developed TYMCOM-X, derived from TOPS-10 but using a page-based file system like TOPS-20.

Copies of DEC's original distribution tapes are available as downloads from the Internet so that a running TOPS-10 or TOPS-20 system may be established.

The KL10 emulation supports v. 442 of the KL10 microcode, which enables it to run the final versions of both TOPS-10 and TOPS-20.

The KS10 emulation supports both ITS v. 262 microcode for the final version of KS10 ITS and DEC v. 130 microcode for the final versions of KS TOPS-10 and TOPS-20.

Implementations expanded to included RSTS, TOPS-10 and TOPS-20 with communications between processors still limited to point-to-point links only.

He became the principal developer of the TOPS-20 mailsystem, and reportedly still runs TOPS-20 systems at his residence.

TOPS-20 began in 1969 as the TENEX operating system of Bolt, Beranek and Newman ( BBN ).

nor was she moved by a letter from Wright pointing out that if he was not `` compelled to spend money on useless lawyer's bills, useless hotel bills, and useless doctor's bills '', he could more quickly provide Miriam with a suitable home either in Los Angeles or Paris, as she preferred.

The headquarters of Morgan was on a farm, said to have been particularly well located so as to prevent the farmers nearby from trading with the British, a practice all too common to those who preferred to sell their produce for British gold rather than the virtually worthless Continental currency.

There was no implication made that their initial reaction ( absence of an arm-elevation ) was less preferred than the presence of levitation.

Greene was in actuality a young ruffian from Kent, who had broken with his parents in order to keep the company he preferred -- pimps, panders and whores.

Woolfson sang lead on many of the group's hits ( including " Time " and " Eye in the Sky ") and the record company pressured Parsons to use him more, but Parsons preferred " real " singers, which Woolfson admitted he was not.

There were a few reasons for this, one of which was political, as the kings of England preferred to appoint bishops from the south to the northern bishoprics, hoping to counter the northern tendency towards separatism.

Their fighting was tense and they did not retreat when disadvantaged by an advancing opposing force and preferred death over defeat.

However, unlike the Spectrum, the single-keypress keyword-entry was optional, and keywords could be entered manually if preferred.

When the date and other obvious clues were removed no significant results were found to suggest there was any preferred chart.

This was the preferred method for protein consumption over animal husbandry, as it required much more work to defend the kept animals against American Indians or the French.

The takeover bid was successively rejected by the Sensi family, who instead preferred to maintain the club's ownership.

He preferred models he was close to, his brother and the artist Isabel Rawsthorne ( then known as Isabel Delmer ).

The baneful influence of these antiquated principles was clearly shown in the maintenance of Königgratz-Josefstadt in 1866 as a strategic point, which was preferred to the defeat of the separated Prussian armies, and in the strange plans produced in Vienna for the campaign of 1859, and in the almost unintelligible Battle of Montebello in the same year.

` Abdu ' l-Bahá's given name was ` Abbás, but he preferred the title of ` Abdu ' l-Bahá ( servant of the glory of God ).

With his wealth, he indulged in custom suits, cigars, gourmet food and drink ( his preferred liquor was Templeton Rye from Iowa

In the 1920s and 1930s almost every major cosmologist preferred an eternal steady state Universe, and several complained that the beginning of time implied by the Big Bang imported religious concepts into physics ; this objection was later repeated by supporters of the steady state theory.

Although she was provided with private art lessons, Potter preferred to develop her own style, particularly favouring watercolour.

Lloyd George offered a degree of support to the Labour government in the hope of winning concessions, including a degree of electoral reform to introduce the alternative vote, but this support was to prove bitterly divisive as the Liberals increasingly divided between those seeking to gain what Liberal goals they could achieve, those who preferred a Conservative government to a Labour one and vice-versa.

It was assumed by the revolutionaries that reactionary and monarchist forces preferred regional languages in an attempt to keep the peasant masses under-informed.

This taste for structural clarity worked its way into the world of music, moving away from the layered polyphony of the Baroque period, towards a style where a melody over a subordinate harmony — a combination called homophony — was preferred.
