Moore's law was at the time a well known trend,
and it wouldn't take a
genius to calculate that the 16-fold increase in memory would be outrun in
just a few years.
Yes, but this goes back to the question of "What was this machine
intended for?". When one examines it in retrospect, and particularly
with a view toward the competition, it's pretty clear that it was
intended as a "home" computer for the kids to play educational games
on and the adults to balance checkbooks and perhaps write letters on.
Given its price, I can certainly appreciate the lack of enthusiasm
from IBM marketing. Indeed, had the same machine been
introduced by,
say, Tandy, at the same price, it would have met with a much cooler
reception.
In case of point, a couple of friends had a garage business
manufacturing high-end bicycle racks. They needed a small office
computer. I had just gotten my 5150 and showed it to them.
Underwhelmed, they went out and bought a Morrow (MD2? MD3?) for less
cash that was loaded with WordStar and (IIRC) Supercalc. It was
ready to go right out of the box. Indeed, there were many other
competitors for the "home office/small business" market that offered
a much better price point and ease of setup when the whole package
was figured in. Eagle II and III boxes come to mind in particular.
Eagle used to hold competitions to see who could get from packing box
to working system in the smallest amount of time--and I think it was
measured in seconds.
I think the 8086 caught on sooner in Japan. Mitsubishi and NEC both
had offerings before the 5150. The NEC APC, in particular, was a
very noteworthy design. Perhaps the need for manipulating Kanji was
part of the picture.
I suspect that if IBM was considering another CPU, it probably was
the 8085. Nice reliable supply (Intel and second sources) and
already used in the System 23 box. Given the market IBM appeared to
be shooting for, there was no chance of a 68K PC. In marketing's
eyes, it would have been overkill.
