Click on "Green Flag" read first screen and hit [Space] Bar. ***NOTE*** Do not change the algorithm to compute the first 1,000 primes, as this was the algorithm that was used to benchmark the older computers. (See ***REMIX*** Opportunity below).
This is a part of Computer History. In the early days of Personal Computers, hobbyists would use the Calculate the First 1,000 Prime Numbers as a benchmark. A Commodore 64 running Logo would do the calculation in over 70 minutes. See the March 1987 Transactor magazine algorithm. See CalcFirst1000PrimesBadCode for a slower and incorrect implementation of the algorithm. ***REMIX*** Opportunity. Run the calculation on your computer and add the time to the list.
