  I recently acquired  a rather aged Compaq
"portable" that defies
 identification, the plate says Model: Compaq, Serial number: 002027. Size
 is 19 1/2 wide, 15 1/2 deep, 9 1/4 high with a 8 in "green screen".On the
 right side to the rear is a sliding cover over 5 slots, 3 filled, the
 left side slides open to expose the fan and switch and provides power
 cord storage. It has two 5 1/4 360k drives. The keyboard locks over the
 front for transport and it has a leather carrying handle on the back. Can
 anyone provide me any info on this machine 
Your description corresponds exactly with the original model Compaq.
A quick ggogle image search showed quite a few photos - boy Comppaq sure
did build a lot of models!
