Oh Dear, no comparison possible of the Tandy/Olivetti and the Atari
"Portfolio": Tandy 100/200 ran on a 8085 CPU, had two banks of (max.
32 KB each) memory, of which one was ROM, the other RAM. The OS was
completely in ROM (in a first, 16 KB modul); and it was completely
different from any DOS-like (the "Portfolio" has some vriation of DOS
2 in ROM, IIRC). There were 4 sockets at all, 2 each for ROM/RAM, and
each of the chips was nearly as expensive as the rest of the machine.
Thus max. storage of DATA - that is, including any program that wasn't
in ROM - was 32 KB. External data storage was originally with any sort
of cassette tape recorder; the battery driven diskette drive came only
late. The cassettes, or the data format on them, were not compatible
with anything else (which was a pity, at the time there was the
Schneider/Amstrad 1512 using standard audio cassettes too).
But they were indeed the first laptop/notebook kind of things, the
Tandy 200 hardly larger/thicker than the better sort of to-day's
such.
