2 unusual facts about IBM Personal Computer/AT


Atari Jaguar

An IBM AT type null modem cable may be used to connect two Jaguars together.

PC-FX

Unlike nearly any other console (except for the 3DO and CD-i), the PC-FX was also available as an internal PC card for NEC PC-98 and AT/IBM PC compatibles.


Banyan Systems

In 1986 the corporation recognized that the IBM PC-AT architecture had become an industry standard, and that lack of VINES support for an industry standard PC server architecture was limiting its sales capabilities, and began work on porting VINES to an Intel 80286-based version of SVR3.

CICS

In 1980, IBM executives failed to heed Ben Riggins' strong suggestions that IBM should provide their own EBCDIC-based operating system and integrated-circuit microprocessor chip for use in the IBM Personal Computer as a CICS intelligent terminal (instead of the incompatible Intel chip, and immature ASCII-based Microsoft 1980 DOS).

Clock rate

The original IBM PC (c. 1981) had a clock rate of 4.77 MHz (4,772,727 cycles/second).

Composite monitor

From the late 1970s stand-alone composite monitors came into use, including by the Apple II, Commodore VIC 20/64/128, Atari, the IBM PC with CGA card, some computers compatible with it, and other home and business computers of the 1980s.

Opera Soft

It released many games for the ZX Spectrum, Amstrad CPC and similar computers in the mid-1980s, but its games were not as popular on the PC.

Plantronics Colorplus

The Plantronics Colorplus was a graphics card for IBM PC computers, first sold in 1982.

PSpice

PSpice was the first version of UC Berkeley SPICE available on a PC, having been released in January 1984 to run on the original IBM PC.

S-100 bus

IBM introduced the IBM Personal Computer in 1981 and followed it with increasingly capable models: the XT in 1983 and the AT in 1984.
