Btw. when 'we' some old dino computer freaks
controlled stepper motors
by DOS machines, we just controlled remoted pics (oldish micro
controllers - but not very old -, I guess you would use DSPs or other
micro controllers today, but would you use your MacOS, Windows, Linux
instead of external chips for fast and exact real-time control?).
Regarding to the age, I should have read who is the sender of the email
before I replied ;D.
