Compaq Portable II First Impressions

During the late 1980s, portable computers were evolving into more laptop forms. The IBM Convertible PC was a good example of it. The Compaq Portable II is very well designed, for a portable PC. It features a fold out keyboard with a recessed cord. It has a power cord compartment which doubles as a stand in the back. There are two doors on the side that slide open, one for the power supply and the other for IO ports. There is a nice faux leather handle, to carry the computer around. The Compaq Portable II is not too heavy, but weighs more than my desktop.

Picture of it closed. You can see the compartment in the middle that holds the power cord and doubles as stand.


There are several IO ports featured on the right side of the computer, for plugging in peripherals like printers. There are two 5.25″ floppy drives in the front.


The keyboard on the Compaq Portable II is nearly full scale, and nice to type on.


The Compaq Portable II has a 9″ green monochrome display. It is very nice and vibrant. It has 720×350 resolution for text mode, and 640×200 for graphics mode.

Operating System

The Compaq Portable II comes with MSDOS 3.1 and can run a wide range of programs.


The Compaq Portable II boots up fairly quickly. I have not tested any program yet, as I don’t possess any or 5.25″ floppy discs.


The Compaq Portable II is a pretty good portable computer for the time. It features many improvements over the original Compaq Portable, especially in size and weight.
