Not sure how to parse this statement, but... The PS/2 (which did indeed stand for Personal System/2) introduced the microchannel architecture. Some of the low end models (25 and 30) were pretty much a rev on the AT and had ISA busses and ESDI harddrive interfaces (but not necessessarily the harddrives themselves). The Mod 25 had an integrated monitor a la the original Macintosh. The higher end PS/2s used MCA busses and SCSI drives, although later models like the PS/2E bowed to the inevitable and uses ISA busses. Someone said that the PS/2 came from the PS/1, in fact it was the reverse, the PS/1 was a "home computer" which came out in 1990 to re-enter the market surrendered by the PCjr. The PS/1 name evolved into Aptiva. The PS/2 nomenclature was more in line with OS/2. The PS/2 line and OS/2 were both announced in 1987, and IIRC concurrently. Nowadays, besides the mouse/keyboard interface, I beleive that more folks associate PS/2 and PS/1 with Sony playstations than with IBM computers. -- Rick DeNatale Visit the Project Mercury Wiki Site http://www.mercuryspacecraft.com/ -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/
