The Compaq Portable 386 was a computer released by Compaq Computer Corporation in 1987.[1] Its street price upon its release was US$12,000–14,000 for a model equipped with an 20 MHz Intel 80386 CPU, 2 MB RAM, 16 kB ROM, 1.2 MB 5¼-inch floppy, 40 or 100 MB hard disk,[1] and a 10" amber colored gas-plasma display.[1] Power is supplied using a mains electricity outlet, a battery exists however just stores the BIOS configuration.[2] Option for Intel 80387 (FPU). An expansion box for two IBM-AT ISA card slots available.[1]

Its RAM is expandable to 10MB via a 32Bit expansion card which also allows the addition of a Modem or additional RS232 Port[2] The expansion card can then accept memory expansion boards for a total of an extra 8MB alongside the four onboard slots that support up to 2MB (4x512KB) SIMMs. The Portable 386 supports one hard disk with up to 504MB of space, which can be configured by the Compaq SETUP disk (BIOS is NOT saved on its EPROMs directly)

Early versions of the Compaq Portable 386 were sold with the Compaq Portable III case and badges. A differing screen bezel stating "386/20" was the only externally visible change.
