Personal System /2, "PS/2"
The Free On-line Dictionary of Computing (18 March 2015):
IBM's second generation of personal computers.
The PS/2 series introduced three advances over the PC series:
3.5" 1.44 megabyte microfloppy disks, VGA and 8514
graphics display standards, and the Micro Channel bus
architecture. The 3.5" disks and VGA can be easily installed
on other PCs and will become the standard for new compatible
computers. The Micro Channel bus allows for multiprocessing
and less aggravation, but cannot be retrofitted to older PCs.
PS/2 models 25 and 30 are ISA, other models have Micro
Channel and ESDI.
