Click on "Green Flag" read first screen and hit [Space] Bar. If you want to run the benchmark without the print, "See inside" the program and look for the comment in the Laptop Sprite Script and move that block aside. ***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). I have found other Prime Number generators on the Scratch website that do the calculation in 11 seconds.
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. Note: The March 1987 Transactor algorithm was implemented incorrectly. The correct algorithm can execute in 0.3 seconds. See CalcFirst1000PrimesCorrected for the correction.. ***REMIX*** Opportunity. Run the calculation on your computer and add the time to the list. If you want to run the benchmark without print, then look at the script in the Laptop sprite, see the comment and move that block aside.
