Editing IBM PS/2 Model 25 (section)

== History ==

IBM announced the PS/2 line on April 2, 1987 with the Model 30 (8086, ISA), Model 50 (80286, MCA), Model 60 (80286, MCA) and Model 80 (80386, MCA). The '''Model 25''' followed on August 4, 1987 as a price-competitive entry aimed at home-office workers and students. Contemporary reviewers compared it favourably to Apple's original Macintosh because of its single-case form factor, although they criticised its lack of a standard hard drive.

The original announcement letter described the Model 25 as a "low price general-purpose computer system which provides enhanced function beyond that established by the IBM Personal Computer," and it was positioned as a direct retail replacement for the IBM PC (5150) and IBM PC XT (5160).

A '''Collegiate''' variant (8525-C02/C05/K02/K05) shipped with two floppy drives, 640 KB RAM, the IBM PS/2 Mouse, DOS 3.30 and Microsoft Windows 1.04. A '''Model 25 LS''' (8525-L01/L04) shipped with a Token Ring network card pre-installed.

The Model 25 286 was announced in May 1990 with a 80286 at 10 MHz, VGA video, a 1.44 MB diskette drive and (on the -036/-G36 submodels) a 30 MB ST-506 MFM hard drive. It was withdrawn from the IBM catalogue on November 17, 1992. The Model 25 SX was developed by IBM Boca Raton's team led by José García and sold only into K&ndash;12 schools from April 1992; it was the only Model 25 with an IDE hard drive interface.
