epatel99✦AI Summary
The Discrete6502 project is a physical, transistor-level reconstruction of the iconic MOS 6502 microprocessor. By scaling the original silicon die layout to an A4-sized board using individual transistors, the creator has built a functional, non-simulated version of the chip that powered early home computers.
A MOS 6502 CPU rebuilt from 4,051 individual transistors — no chips, no FPGA — laid out so the board reproduces the original silicon die, transistor for transistor.
