The Antikythera Mechanism(PreComputers / Machines)
1)Can calculate dates
2)Can predict astronomical phenomena
3)Is considered as the earliest analog computer
4)Can predict eclipses and astronomical positions for calendar
5)Astrological purposes Overall, the Antikythera mechanism is an very useful ancient Greek mechanical device used to display and calculate information about astronomical phenomena. I think it is a great milestone for the ancient computer.

The Punched Card System(Early First Computers / devices)
1)Developed by Joseph-Marie Jacquard
2)Widely used in the 20th century
3)Still in use today
4)Used in many places like (music machines, mechanical organs, calculators, mechanical counters, looms, and other automatons and early computers.) Many early digital computers used punched cards, often prepared using keypunch machines, very helpful for both computer programs and data.
