I think that commodore went wrong in three areas.
1. they never put a standart rs232 port on their stuff. sure you could
use 1488's , but that was not the point. There was no real rs232.
True... I have much the same moan about certain HP machines where the
HPIB port is built-in (or an easy-to-find module), but the RS232 port is
almost impossible to find now.
2. The disk drives were basically computers to themselves;
Have you ever opened an HP91xx drive box? There's normally a 68B09 inside...
3. 40 columns just ain't cool. 80 is the way to go.
Yes, but rememebr that Commodore were going for the home market, and
wanted to be able to use a normal TV set as a monitor. I've not found a
TV that can legibly display 80 columns if you feed the signal in to the
aerial input (composite video inputs were not at all common then).
