An old 1970’s computer that still works and can still go on the modern day internet. Comes to show computers and electronics were made to last back then. Not the crap we buy nowdays that only lasts 3 - 4 years. Probably not even that.
And the processor in Xerox Alto is not a single chip processor its a multiple chip processor using TTL chips and its CPU clock rate is 5.88 MHz which is very lesser than compare to our modern computer CPU clock rate which is 800MHz, 900MHz, 1.0GHz, 1.5GHz, 2.0GHz, 3.0GHz, 5.0GHz, etc.
the amazing feature (replay mode) not exist today what a shame! However, those people created a legacy where all people around the globe still using until today. Also I hope we will have some seminar regarding the history of implementing the languages to the computer's application since I believe it was a huge challenge back in those days.
Seriously, no matter how somber/inappropriate there will always be some random person who brings their child and then can't control them. Ever hear of a nanny/babysitter?
