Compaq Deskpro 286

No, the original 1984 Deskpro was an 8086-based XT-class machine, while the Deskpro 286 was a later AT-class model using Intel's 80286 processor. The distinction matters because the 286 supports protected mode and a different memory architecture.

The Deskpro 286 uses Intel's 80286, commonly running at 8 MHz in early configurations. The 80286 was the processor used in IBM's PC AT and became a major standard for business PCs during the mid-1980s.

The 80286 architecture could address up to 16 MB in protected mode, but early Deskpro 286 systems were normally sold with far less memory. The advertised architectural limit should not be confused with the RAM capacity of a specific Compaq configuration.

MS-DOS was the usual operating system, with later configurations also able to run software such as IBM OS/2 or compatible Unix variants. The 80286's protected mode made it more suitable for advanced operating systems than an 8086, although ordinary DOS software remained dominant.
