help Compaq Portable FAQ

Why was the 1983 Compaq Portable important to IBM PC compatibility?

The Compaq Portable was one of the first successful IBM PC compatible computers and shipped in 1983. Compaq famously used clean-room reverse engineering to create a compatible BIOS without copying IBM's code.

Was the Compaq Portable actually portable?

It was portable in the luggable sense, not like a modern laptop. The machine weighed about 28 pounds and had a suitcase-style case with a built-in 9-inch monochrome CRT monitor.

What operating system did the Compaq Portable run?

It ran PC-DOS and MS-DOS software intended for the IBM PC ecosystem. That compatibility mattered because buyers could use major business programs of the period, including Lotus 1-2-3.

How was the Compaq Portable different from the Osborne 1?

The Osborne 1 arrived earlier, in 1981, but it was based on CP/M rather than IBM PC compatibility. The Compaq Portable was more important for the DOS business market because it could run IBM PC software.
