The 6502 Single Board Development System - Some Disassembly Required

The 6502 Single Board Development System - Some Disassembly Required Some time ago, i made a simple, happy go lucky 6502 computer. i called it a minimal development board because that’s exactly what it was: the absolute bare minimum you could get away with. it was an invaluable tool for getting to grips with 6502 system design and very little else as it turns out. This is a compact disassembler for the 6502 cpu in just 100 lines of code (plus data tables for opcodes and rom image in separate include files). the program has a simple shell.

6502 Minimal Development Board - Some Disassembly Required

6502 Minimal Development Board - Some Disassembly Required This is a collection of 6502 software disassembly projects. the machine language code and embedded graphics have been converted to readable form with 6502bench sourcegen, a disassembler for code written in 6502, 65c02, and 65816 assembly language. They broke away and joined mos technology, a calculator manufacturer, to help produce one of the most revolutionary pieces of silicon to ever roll off a drawing board. the main idea was to simplify a chip design as much as possible by removing everything but the bare necessities. Easy 6502 single stepping based on steve wozniak's circuit in the apple 1 manual. hook up 5v gnd and the three signals to your 6502 cpu and watch it halt after each instruction even running at several mhz. no matter if it's an nmos 6502 from 1975 or a cmos from 2024. After gaining some practical experience, i found it far too limited to be useful. instead, i moved over to my new single board development system which is about as complicated to build yet far more valuable for 6502 system design.

So yesterday i wrote one, mos 6502 instruction set only (though an update to 65c02 should be quite simple), and outputs standard disassembly like the old monitors. attached along with the source is a compiled version for windows users (command line). 6502 cross development tool: this site contains links to a large number of 6502 cross development tools including assemblers, c compilers, disassemblers and more. This is my hackaday prize summary video for the 2022 hackaday prize. for the full overview watch: • my 6502 sbc r1 complete hardware over more. This repo contains kicad schematics, netlist, layout and gerber plots for the pcb, as well as a parts list, the firmware and a port of microsoft basic. the board is fully functional and all parts (or equivalent alternatives) are readily available as of nov '21.
