  IBM 700/7000 series - Wikipedia, the free encyclopedia
The IBM 700/7000 series was a series of incompatible large scale (mainframe) computer systems made by IBM through the 1950s and early 1960s.
The IBM 7094, with seven index registers had a "compatibility" mode to permit programs from earlier machines that used this trick to continue to be used.
The IBM 702 and IBM 705 were similar and the 705 could run many 702 programs without modification, but they were not completely compatible.

 IBM Archives: 705 Data Processing System
The IBM 705 was one of the most powerful data processing systems available in the mid-1950s.
The usual means of input of data to the 705 system was magnetic tape, but entry could also be effected by a punched card reader, or, when special instructions were required, from the operator's console.
This enables the 705 to increase its ability to read and interpret its instructions by a factor of almost seven with respect to the 702.

 The history of the Mainframe
A good source for IBM history is their Reference section.
In a 1954 IBM publication, the 705 was credited with "Forty thousand or twenty thousand characters of high-speed magnetic core storage; Any one of the characters in magnetic core storage can be located or transferred in 17 millionths of a second; Any one of these characters is individually addressable."
The IBM 1401 was called the Model T of the computer business, because it was the first mass-produced digital, all-transistorized, business computer that could be afforded by many businesses worldwide.

 The IBM 701
The first unit was installed in 1952 at IBM Headquarters in New York City, replacing the SSEC.
The IBM 700 series were binary (as opposed to decimal) vacuum-tube logic computers with 36-bit words.
The 701's vacuum tubes were collected into "pluggable units", a concept introduced with IBM's 604 Electronic Calculating Punch in 1948, which simplified troubleshooting and service of machines that had hundreds or thousands of tubes.

 Doug Jones's punched card codes
IBM's BCD codes were all more complex, partly because of a desire to represent the numeral zero with the 6-bit numeric code 000000 (in the IBM 704, 709, 7040 and 7090) or with 001010 (in the IBM 705, 7080, 1401, 1410 and 1414).
The IBM model 026 keypunch, introduced in July 1949, was the workhorse of much early work in business data processing, and although it was incapable of automatically punching the large character set required by most programming languages, many model 026 punches remained in use into the early 1970's.
Given the sparse nature of the IBM 026 character set and the larger character sets supported by printers of the era, many computer manufacturers developed proprietary extensions of their own, some with a great degree of compatability with IBM's later character set extensions, and some with little or no compatability.

 BRL Report 1961
IBM 1401C with 1402, 1403 and two 729 requested (now pending) to replace card reader, punch and EAM equipment and intended to divert from 705 some of smaller jobs.
The IBM 1401 equipment requested consists of: 1 1401/C3 Processing Unit 1 14021 Card Read Punch 1 14032 Printer 4 729 II Tape Units The IBM 1401 Processing Unit will be equipped with four special devices which provide for high-low-equal compare, multiply-divide, print storage, and advance programming.
These are to be used in conjunction with the IBM 705 Systems to relieve the large scale computers of the less involved processing, particularly in editing and sorting operations.

The 704, and IBM 709 which had the same basic architecture, represented a substantial step forward from the IBM 650's magnetic drum storage as they provided random access at electronic speed to core storage, typically 32k words of 36 bits each.
The IBM 705 was the business counterpart of the 704.
Very few 700 series computers remained in service by 1965, but the IBM 7090, using transistors but similar in logical structure, remained an important machine until the production of the earliest integrated circuits.

This was a machine developed by IBM expressly for the new Social Security program and deployed to this task in early 1937.
According to the IBM account salesman, H.J. McDonald, IBM President Tom Watson had ordered the development of the Collator because he was concerned that the government would not otherwise be able to meet its obligations under the new Social Security program.
The 705 gradually took over most of the accounting functions associated with the Social Security program, and continued in use until the 1960s when later generations of electronic computers replaced it.

 2001 Newsgroup postings (01/19 - 02/20) Lynn Wheeler
It probably wasn't until near the end of the summer that anybody from ibm bothered to even mention that there was something else besides OS/PCP (and the BPS loader deck that I had accidently stumbled across).
For cp/67 and vm/370 the method used was to run the hypervisor in non-translate (real) addressing mode and rely on the PSW bit to switch from relocate mode and non-relocate mode and at the same time for a PSW bit to switch between supervisor state and problem state...
Each could do I/O. At the time, the IBM shop next door had "clusters" of processors that shared peripherals but not memory (Attached support processors - ASP) and I believe there was a some model of the 360 that supported "attached proccesors" which were sort of like the predecessors of numeric co-processors (no I/O capabilities).
