A simple 6502 Single Board Computer based on Grant Searle's 6502 Computer. The only real differences between Grant's design and this computer are the use of a GAL16V8 for 'glue' logic to reduce the chip count and the addition of a 6522 VIA for parallel I/O.
Grant's original firmware has been modified to add a 6502 System Monitor based on SyMon III. Assemble the firmware with the Macro Assembler AS
