OVERVIEW HIGHLIGHTS
o New, price-performance standard in an Intel 80286-based personal
computer
o 640 KB memory on the system board
o Enhanced PC Keyboard
o Supports both 3.5" and 5.25" Internal Diskette Drives
o 20 MB fixed disk file
DESCRIPTION
A 20 MB fixed disk and a 1.2 MB 5.25" diskette drive are
standard on the PC XT Model 286. One additional diskette drive may
be internally installed as the B drive from the following new
offerings:
o One 3.5" Internal Diskette Drive (mutually exclusive with the
4865 Model 2, 3.5" External Diskette Drive).
o One High Capacity Diskette Drive
o One 5.25" 360 KB Diskette Drive
New special features further enhance the performance and
function of the PC XT Model 286.
3.5" INTERNAL DISKETTE DRIVE
This feature is a half-high, double-sided, 3.5" diskette drive that
supports the 3.5" media with 720 KB of storage capacity. The drive
utilizes the standard fixed disk and diskette drive adapter provided
on the PC XT Model 286. When installed, the drive becomes the "B"
drive. Initial Program Loading (IPL) from the 3.5" diskette is not
supported by the PC XT Model 286. For operation, DOS users require
DOS 3.2 on a 5.25" diskette or fixed disk. The 3.5" Internal
Diskette Drive is mutually exclusive with the 4865 Model 2, 3.5"
External Diskette Drive.
HIGH CAPACITY DISKETTE DRIVE
The High Capacity Diskette Drive is a half-high, 5.25", dual-sided
drive with 1.2 MB of storage capacity. This drive is compatible with
the standard drive provided with the PC XT Model 286 in the "A"
position. When installed as the second drive, the High Capacity
Diskette Drive becomes the "B" drive. This drive utilizes the
standard fixed disk and diskette drive adapter provided on the PC XT
Model 286.
5.25" 360 KB DISKETTE DRIVE
This half-high, 5.25" diskette drive permits the exchange of
information between the PC XT Model 286 and other members of the IBM
PC family. The drive is a dual-sided drive with 360 KB of storage
capacity. When installed, the drive becomes the "B" drive. This
drive utilizes the standard fixed disk and diskette drive adapter
provided on the PC XT Model 286.
SYSTEM PERFORMANCE
The IBM PC XT Model 286 processor is up to 2.5 times faster
internally than the prior PC XT family and up to 20 percent faster
than the Personal Computer AT (R) Model 239, depending upon specific
applications.
