<> Sounds bogus. The small laptops using 8080 (actually 8085) were the tand
<> M-100s and there were also the Epson and NEC but none were before 1979.

Most of the early laptops were either 8085 or z80 as both required less
support chips than the 8080 (8080+8224+8228) as the 8080 chip set required
three voltages and lots of board space. the 8085 or z80 were single 5v
at lower power needs. the 6502 was also popular for the application.

<On the subject of early laptops in general, I have heard much in praise
<of the Tandy model 100, but I like the Epson HX20 which has everything
<you could possibly want in a laptop except a decent sized screen!

Tandy improved the 100 with the 102 which has a lager screen.
