Hey, what good is collecting old computers if you can't chip in
technical data?

HP Portable: DC
GRiDPAD 1910:  DC
Macintosh Portable (original): DC
Timex Sinclair 1000: DC  (ok, it's not a laptop)
and, the granddaddy of them all, TRS-80 Model 100: DC

(those are the ones lying around the office just now :)
