== Use for training, prototyping, and general hardware education ==
8-bit processors continue to be designed today for general education about computer hardware, as well as for hobbyists' interests. One such CPU was designed and implemented using [[7400-series integrated circuits]] on a [[breadboard]].<ref>{{cite web|first=Daniel|last=Oberhaus|title= This Guy Designed and Built an 8-bit CPU from Scratch|website=[[Motherboard (website)|Motherboard]]|date=February 9, 2019|url=https://www.vice.com/en/article/a34ege/diy-8-bit-cpu|access-date=November 4, 2021}}</ref><ref>{{cite AV media|url=https://www.youtube.com/watch?v=g_ZaioqF1B0|title=Homebuilt 8-bit CPU + Computer with graphics and sound made from scratch using 74HC Logic|first=Paulo|last=Constantino}}</ref> Designing 8-bit CPU's and their respective assemblers is a common training exercise for engineering students, engineers, and hobbyists. [[FPGA]]'s are used for this purpose.
