Zik80 Basic specification:
CPU: eZ80 (reasonably modern descendant of the beloved Z80 cpu from the 1980s)
GPU: STM32 microcontroller (F2 or F4 are fine) - a general purpose mcu that we abuse into a graphics generator
RAM: 128KB or 256KB or 512KB (easy to add more to the design, but settled on a workable amount for a retro-styled machine)
ROM: Uses cartridges! Each cartridge can be up to several MB in size .. 8bit CPUs of the 80s could only dream..
Ins and Outs: VGA output (full colour), PS/2 keyboard, Atari-style joysticks, classic era sound chip (AY-3-8910, YM2149); multiple serial ports
Expansion options are plentiful .. some GPIO headers are exposed; i2c bus exposed; serial; the cart slot with full bus and 3.3V and 5V power feeds; USB pads exposed; and more! Designed for hackability! Reflash the eZ80, the STM32, or even the cartridge on the fly to change how the CPU and GPU work, or program your own cartridges!
