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.
- 8MHz CMOS Z80
- 5-slot active backplane, USB powered
- 32KB ROM, 16KB RAM, 16KB double buffered VRAM
- 64 color 640×480 VGA graphics
- PS/2 keyboard, ESP8266, SD card, I2C EEPROM, RTC, UART, Timers
