bisync
(Bisynch) An IBM link protocol, developed in
the 1960 and popular in the 1970s and 1980s.
Binary Synchronous Transmission has been largely replaced in
IBM environments with SDLC. Bisync was developed for
batch communications between a System 360 computer and the
IBM 2780 and 3780 Remote Job Entry (RJE) terminals. It
supports RJE and on-line terminals in the CICS/VSE
environment. It operates with EBCDIC or ASCII {character
sets}. It requires that every message be acknowledged (ACK)
or negatively acknowledged (NACK) so it has high
transmission overhead. It is typically character oriented and
half-duplex, although some of the bisync protocol flavours
or dialects support binary transmission and full-duplex
operation.

ibm 370
(foldoc) | System/370
IBM 370
(S/370) An IBM mainframe computer
introduced in 1970 as a successor to the IBM 360.
Enhancements included the ability to support virtual memory
and improved main storage. Two models were available
initially: 165 and 155, with cycle times of 80 and 115
nanoseconds.

IBM390
IBM zSeries
(Enterprise System Architecture) An IBM
mainframe computer introduced in 1988. Successor to the
IBM 370XA had enhanced access registers that allowed access
to other forms of virtual memory. This enhancement allowed
more data storage in main and virtual memory, reducing I/O
operating and improving speed and efficiency. The IBM 370ESA
was rebranded as the IBM390, and later as the zSeries.

enhanced address space.

pga370
(foldoc) | Socket 370
PGA370
(PGA370) A physical and
electrical specification for a motherboard processor
socket. Socket 370 uses a square SPGA ZIF socket with 370
pins, arranged 37x37 (sometimes described as 19x19).
Intel originally designed Socket 370 for PPGA Celeron
processors. Newer Socket 370 motherboards additionally
support FC-PGA Celeron and Pentium III processors.
The difference between the two versions is electrical;
some pins are used differently and voltage requirements have
been changed from Intel's VRM 8.2 to VRM 8.4. In
addition, Celeron processors require a 66 MHz front side bus
(FSB), and Pentium III processors require a 100/133 MHz FSB.
Some older Socket 370 motherboards support VRM 8.4 and
variable bus speeds, so adapters are available that convert
the socket pinout to allow FC-PGA processors to work.
VIA's Cyrix III processor was designed to work with
Socket 370 motherboards.
