The parallel port interface was originally known as the Parallel Printer Adapter on IBM PC-compatible computers. It was primarily designed to operate printers that used IBM's eight-bit extended ASCII character set to print text, but could also be used to adapt other peripherals.
The original IBM PS/2 mouse PS/2 connection ports (later colored purple for keyboard and green for mouse, according to PC 97) were once commonly used for connecting input devices. PS/2 systems introduced a new specification for the keyboard and mouse interfaces, which are still in use today (though increasingly supplanted by USB devices) and ...
An IEEE 1284 36-pin female on a circuit board. In the 1970s, Centronics developed the now-familiar printer parallel port that soon became a de facto standard.Centronics had introduced the first successful low-cost seven-wire print head [citation needed], which used a series of solenoids to pull the individual metal pins to strike a ribbon and the paper.
Two, 16 bit MCA slots (top and middle). At the bottom is an MCA slot for an IBM 8514 card.. Micro Channel architecture, or the Micro Channel bus, is a proprietary 16-or 32-bit parallel computer bus publicly introduced by IBM in 1987 which was used on PS/2 and other computers until the mid-1990s.
The stock configuration of RAM on IBM P75 is 8 MB. [8] The IBM P75 featured numerous ports, including an external SCSI connector, a parallel port, a serial port, a PS/2 mouse port, an external 5.25" floppy disk port, and a VGA port. The ports are housed behind a door on the rear of the unit which allows for them to be hidden when not in use.
Parallel ATA (PATA), originally AT Attachment, also known as Integrated Drive Electronics (IDE), is a standard interface designed for IBM PC-compatible computers.It was first developed by Western Digital and Compaq in 1986 for compatible hard drives and CD or DVD drives.
Industry Standard Architecture (ISA) is the 16-bit internal bus of IBM PC/AT and similar computers based on the Intel 80286 and its immediate successors during the 1980s. The bus was (largely) backward compatible with the 8-bit bus of the 8088-based IBM PC, including the IBM PC/XT as well as IBM PC compatibles.
The latter two features lower the L40 SX's power draw. The back of the L40 SX sports one serial port, one parallel port, an external AT expansion port, a VGA port, and a PS/2 mouse port. IBM provided an optional modem that can receive fax transmissions. [11]: 11
