TI-99/4A Primes

BASIC, mathematics, programming, #old hardware, #prime, #prime generation, #Texas Instruments, #TI

Being a fan of old hardware, I used the TI-99/4A (released in 1981) to calculate some primes.
The code is written in BASIC, the programming language found on most computers of this era.
Further information on the TI can be found in this Wikipedia article.

Using the programming features given on Texas Instruments’ graphing calculator TI-84 Plus, I created this text-base connect four game.
The code is written in BASIC and can be seen below.
To transfer code to and from the graphing calculator, I used Texas Instruments’ TI Connect™ CE Software [1].

Controls

  • Numbers 1 to 7 put your piece accordingly,
  • ‘clear’ pauses the game (for taking screenshots).
