Here are my favorite list of old (more than 20 years old) PC portables:

Number one - a Compaq Portable (with an Intel 8088 CPU):


Number two - an IBM PC Portable (Type 5155, with an Intel 8088 CPU):


Number three - a Compaq Portable II (with an Intel 80286 CPU, AT compatible):



Number four - a Compaq Portable III (also with an Intel 80286 CPU, AT compatible):

Most innovative, with a Gas Plasma Screen, really portable.
Picture shows Windows 3.0 running ;-)

My favorite portable PC here - NUMBER 3 !
Still fast enough for Word for DOS 5.5, reliable, and artless ;-)

WHAT'S YOUR FAVORITE ONE ?
