  GE-600 series - Wikipedia, the free encyclopedia
GE built a machine called the M236 for the task, and as a result of the 36-bit needs, it ended up acting a lot like the 7094.
However by the early 1960s GE was the largest user of IBM mainframes, and producing their own machines seemed like an excellent way to lower the costs of their computing department.
GE sold its computer division to Honeywell in 1970, who renamed the GE-600 series as the Honeywell 6000 series.

 GE-600 series
However by the early 1960s GE was the largest user of IBM mainframes, and purchasing their own machines seemed like an excellent way to lower the costs of their computing department.
In fact both machines had identical core CPUs, but the 635 had two of them, in what is likely the first example of a general purpose SMP system.
GE then decided to sell their entire computer division to Honeywell in 1970, who renamed the now working GE-655 as entire line as the Honeywell 6000 series.

 GCOS - FOLDOC Definition
GE Information Service Divsion developed a large special multi-computer system that was not publicised because they did not wish time sharing customers to challenge their bills.
Although GE ISD was marketing DTSS - the first commercial time sharing system - GE Computer Division had no license from Dartmouth and GE-ISD to market it to external customers, so they designed a time-sharing system to sell as a standard part of GECOS-III, which replaced GECOS-II in 1967.
The GE-645, a modified 635 built by the same people, was selected by MIT and Bell for the Multics project.

 dtss - definition by dict.die.net
GE's Information Service Divsion (ISD) marketed DTSS which was running on a system called GE-265 (a combination of the front-end processor the Datanet-30 and the GE-235).
DTSS was ported (and significantly improved by GE ISD around 1965-1966 on a combination of DN-30 and GE-635).
This proprietary system, called Mk-II, later improved by GE and renamed Mk-III, is still working today (1997) as part of the GE service bureau that also includes IBM and Unix computers.

 GE 635   (Site not responding. Last check: 2007-10-29)
Technically, the first computer I used was a General Electric 635 mainframe.
(You may not have known that General Electric ever made computers; GE sold its computer line to Honeywell long ago.) I didn't use the 635 much at all, but since we computer people are sticklers for accuracy, we've got to count it.
Before I got too deeply into the 635, I switched to using my high school's Honeywell 1640.

 Multics History
The GE proposal was chosen and the contract signed in August 1964.
The GE-645 was an enhanced version of the commercial GE-635, which in turn was a descendant of the GE M236 machine that GE had supplied to the US Air Force in the early 60s.
Some GE personnel in Phoenix, where the hardware was built, accessed the system via GE's private phone network.

Mistakes in coding the tables combined with bugs in the IDS code itself were a rich source of fatal errors that caused the system to crash, several times a day.
B.F. Goodrich bought the rights and converted it to run on the IBM family of mainframes and renamed it IDMS in the process.IDS for the GE-200 was written in the language of the General Assembly Program (GAP).
The GE FORTRAN II compiler was written in WIZOR as well as the WIZOR compiler itself.

The earliest version of the Dartmouth time-sharing operating system was loaded by undergraduates—who assisted in designing the system—onto a GE 235 and Datanet 30 in early 1964.
General Electric later sold this hardware and software system as the GE 265, and the associated time-sharing service became commercially available as the GE Mark I. That same year the National Science Foundation awarded Dartmouth a grant for further development of the network and to facilitate its use in undergraduate education.
In 1966, Dartmouth students replaced the GE 235 with a GE 625 processor for time-sharing.

In fact, GE funded the venture, buying 10% of Honeywell stock which was held in a mandated non-voting trust and divested after ten years.
The x25 and x15 models were derived by slowing the clock by factors of 2 and selling to different price points (with decreased mean time between falure due to the slower speed).
The GE 600 Series was adopted for the MULTICS project at MIT as the GE 655.

 [No title]
A GE team under Tom Kinhan was working on FL, a very fancy full-macro assembler, but we needed an interim assembler in a hurry in 1966 or 1967, so Bill Poduska wrote EPLBSA, the "EPL Bootstrap Assembler." EPL compiled into EPLBSA, which was then assembled into Multics object segments.
The 635 was derived from the GE M236 computer supplied by GE to the US Air Force in the early 60s.
Project MAC had a 635 in the same 9th floor machine room at Tech Square as the 7094 that CTSS ran on, and programmers generated GEIN tapes using the CTSS MRGEDT command, which called a special supervisor trap to write a tape in 635 format.

 Re: ge635-emulator development
The 645 seems quite similar to the 635 in electronic design (just add an appending unit, what could be simpler?), but the way in which it supports mid-instruction restarts is delicate and subtle.
I suspect the 635 is significantly simpler to emulate.

 Multics Virtual Memory - Tutorial and Reflections
One "improvement" GE made was to allow any number of levels of indirection, whereas Organick says that the 7094 stopped after two memory references.
The 635 and 645 repeat (and repeat-double) instructions WERE interruptible, but only after each instruction or pair of instructions.
The existing 635 FT ("fault tag") IT modifier was renamed to FT1 ("Fault Tag 1") and a new tag was added to indicate that an ITS pointer was invalid; it was named FT2 ("Fault Tag 2") and was used within Multics to implement dynamic linking.

 Fernando J Corbató
Initially the basic system chosen was the newly marketed GE 635.This computer was similar to the IBM 7094's which Project MAC and Bell-Labs already had experience with, both machines had the same 36-bit word, accumulator, quotient register, index registers.
Due to the significant changes in hardware (The GE 635 became the GE 645) which were needed to implement some of the advanced features which Multics would incorporate there were no assemblers or compilers for the machine available.
Problems were found when trying to modify an existing assembler from the related GE 635.

I started with GE as a technician in 1960 right out of the USN (was a gunnery fire control Tech) and worked mainly on experimental Radar's and other military projects until 1964 (see 1964 below).
I worked in field service on the GE 115, 200, 400 and 600 series computers and also the origin of the 600 series the M236 made in Syracuse, NY for the USAF's Space Track program sites at Shemya AFB Alaska and Diyarbakir Turkey.
In 1981 I left GE for Systems Development Corp. (SDC) at VAFB as senior Engineer and site manager of a complex of 14 SEL model 3277 systems for 2 years then as repair depot lab manager of SDC.

 General Comprehensive Operating System - Wikipedia, the free encyclopedia
One of the hallmarks of the true second generation of this OS was its support of Time-sharing ("TSS") along with batch.
After the buy-out of GE's computer division by Honeywell, GECOS-III was renamed GCOS-3, and the hardware line was renamed to the H-6000.
Later Honeywell Marketing created a "Series" 60, and renamed the H-6000 to the Level-66.

 Historia de Unix: Relato evolutivo de Unix
The collaborative project by GE, MIT and ATandT to create a computer operating system that would be called Multics (1965-68) was to "show that general-purpose, multiuser, timesharing systems were viable." (See Douglas Comer, "Pervasive Unix: Cause for Celebration," Unix Review, October, 1985, pg.
When the decision to pull out of the Multics project was made by ATandT, Vyssotsky explains there was an operating system that he called a "precursor of Multics" running on their GE 645 computer.
These tapes were carried from the GE machine to the PDP-7 for testing until a primitive Unix kernel, an editor, an assembler, a simple shell (command interpreter), and a few utilities (like the Unix rm, cat, cp commands) were completed.

 Douglas W. Jones's collection of punched cards for computer programs
This card, probably designed in October 1965 (judging by the notation "10-65" printed on the left edge), was printed for use with the GE 600 series computers at Bell Labs.
These included a GE 635 at the Whippany lab and two GE 645 systems at Murray Hill, one in the computer center, and one used for the Multics project, a joint venture between Bell Labs, MIT and GE.
This card is formatted for the GE 600 assembly language, and it has the nice feature that columns 50 to 72 are printed with complete documentation of the GE 600 6-bit BCD character set, as it was punched on cards.
