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tape data storage format designed to work with the IBM 7074, 7080 and 7090 computers that was introduced in 1961 and withdrawn in 1971.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 Personal Computer, commonly known as the IBM PC, spanned multiple models in its first generation (including the PCjr, the Portable PC, the XT, the AT, the Convertible, and the /370 systems, among others), from 1981 to 1987.

[21] In terms of competition, while the Copier I was faster than the Xerox 914 (which ran at 7 copies per minute) [22] it was reported as competing with the desktop Xerox ...
The Adam printer computer used daisy wheel printing, giving a higher quality print than most dot-matrix printers of the time. The print ribbon was a one-time ribbon, of the type also used by IBM Selectric typewriters. The one-time ribbon produced better quality print than reusable ribbons, but they needed to be replaced more often.

The first known computer to be produced by Leading Edge is the Model M, released in 1982. By 1986 it sold for $1695 (US) with a monitor and two floppy drives. It used an Intel 8088-2 processor, running at a maximum of 7.16 MHz on an 8 bit bus, compared to 6 MHz for the IBM PC-AT on a 16 bit bus. The 'M' stands for Mitsubishi, their parts provider.
