Overview
etc-nand is a real-world ETC.A CPU built from almost only quad NAND gate ICs (74hc00)
It will probably be finished in a few months.
Estimates
Estimated gate count:
- 2800 NAND gates
- 320 tristate buffers
Estimated component counts:
- 700x 74hc00 quad NAND gates
- 40x 74HC54 octal tristate buffers
- a few simple resistors
Planned Specifications
ETC.A base instruction set + byte operations + S&F + Von Neumann
The CPU will communicate with peripherals over a 16 bit data + 15 bit address memory bus
Purchase
You will be able to purchase one in the future.
Stay tuned!
