FAP80 is a Homebrew Computer Built with Zilog Z80 CPU
Designed over the course of a year dekuNukem built – twice! – this homemade ‘FAP80’ computer. Short for FPGA Assisted Processor, FAP was originally designed with numerous through-hole components on breadboard and perfboard (below, left) before being redesigned with SMT and custom PCBs. The stats – 8MHz CPU, 16KB RAM – might not be much compared to modern cellphones or even an Arduino Uno (16MHz, 32KB flash) but this is nothing short of an impressive build, a life achievement no doubt.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
