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.
