The IBM 7340 "Hypertape" system was a magnetic tape data storage format designed to work with the IBM 7074, 7080 and 7090 computers that was introduced in 1961 and withdrawn in 1971. As a technology, it deviated in several ways from the then dominant IBM 7 track system. It distinguished itself by having higher capacity, faster data transfer ...
The IBM 7340 Hypertape drive, introduced in 1961, used a dual reel cassette with a 1-inch-wide (2.5 cm) tape capable of holding 2 million six-bit characters per cassette. [ citation needed ] In the 1970s and 1980s, audio Compact Cassettes were frequently used as an inexpensive data storage system for home computers , [ b ] or in some cases for ...
A reel of half-inch magnetic tape being loaded onto an IBM 729 tape drive that is attached to an IBM 1401 being restored at the Computer History Museum. IBM 's first magnetic-tape data storage devices, introduced in 1952, use what is now generally known as 7-track tape.
The 7070, 7072 and 7074 support a variety of peripheral devices. including up to 1 7150 console typewriter, 4 7300 Disk-Storage units attached to an IBM 7604 Tape Control via an IBM 7605 RAMAC Control, 40 729 models II and IV [c] tape drives attached to an IBM 7604 Tape Control, and 6 (3 input, 3 output) unit record devices attached to an IBM ...

IBM 7010 system: console (in front), disc drives and processing modules (left), tape storage, punch card reader and printer (right) The 700/7000 commercial architecture inspired the very successful IBM 1400 series of mid-sized business computers. In turn, IBM later introduced a mainframe version of the IBM 1410 called the IBM 7010. Data format
The IBM 729 Magnetic Tape Unit was IBM's iconic tape mass storage system from the late 1950s through the mid-1960s. Part of the IBM 7-track family of tape units, it was used on late 700, most 7000 and many 1400 series computers.
In 1995 IBM introduced a card, the "Enhanced S/390 MicroProcessor Complex", which supported IBM ESA/390 architecture on a PC-based system. [20] IBM's PC-related products evolved to support that as well, employing the card (IBM part number 8640-PB0) in the "IBM PC Server 330 in 1998 [21] [22] and the IBM PC Server 500 models. [23]
