The Compaq Portable 486 is a computer released by Compaq Computer Corporation in 1991. It was the last portable computer/"luggable" released under the Compaq Portable series of computers.
The computer was released in several models with different hard disk configurations and in two screen types, a cheaper monochrome version and a more expensive active matrix color version, known as the Compaq Portable 486c. The street price with a 120 MB hard disk was US$5,899 (equivalent to $13,600 in 2024) for the monochrome version and US$9,999 (equivalent to $23,100 in 2024) for the active matrix color version. For a model with a 210 MB hard disk, the price was US$6,899 for the monochrome version and US$10,999 for the active matrix color version, available after May 1992.
Both versions are equipped with a socketed 33 MHz Intel 80486DX CPU, 4 MB DRAM (72-pin SIMM), 1.44 MB 3.5" floppy, 120 - 1000 MB hard disk drive (P-ATA), and SCSI port for CD-ROM or tape. On the front of the unit there two dials underneath the PC-speaker to adjust the brightness of the screen and the volume of the PC-speaker. The PC-speaker in the Compaq Portable 486 is unique in that there is a 3.5 mm audio input jack on the side of the unit to allow a third party ISA sound card to pass through its audio output to the PC speaker.
Compaq released two versions of the Compaq Portable 486 with a faster, 66 MHz Intel 80486DX2 CPU, named the Compaq Portable 486/66 for the monochrome version and the Compaq Portable 486/66c for the color version.
Compaq worked with Network General which released branded versions of the Compaq Portable 486 as "Network Sniffers".
A case-modified version of the colour screen variant with replaced internals was used as a prop in the 1995 film Hackers. With its internals replaced by those of a Macintosh laptop, it served as the character Dade Murphy's (Aliases: Zero Cool and Crash Override) primary computer for the first half of the film.
