6502brick

A 6502 dev board usable with multiple popular projects

This board features a 65C02 CPU, 32K RAM, 32K ROM (16K mapped by default), a 65C22 VIA and a MC6850 ACIA. A 40 pin header is available with address, data and control signals to extend the board more, or to connect a logic analyzer. Like Ben Eater's amazing video's, a button is available for single stepping.

The memory map and interrupts are controlled via GALs for flexibility
