A simple modulator replacement for Commodore 64s with "longboards", complements my Lumafix version as well adding an audio connector for second SID.

RC6502-Apple-1-Replica

An expandable SBC-version of the Apple 1 computer, easy to get started with and lot of cool stuff that can be added to it!

BE6502-Build-a-65c02-computer

A PCB being made while watching Ben Eaters "Build a 6502 computer" video series. Includes the computer itself, a standalone slow clock and an Arduino Mega shield for the bus monitor sketch..

C++

C64-Pi1541-II

I wanted a Pi1541 module that did not feel like I was handling bare electronics, so I made one that hides most of the scary bits (no 3d-printer required).

C64-BlinkenDiag

A version of the DIAG64cart, this mainly changes components for the ones I've already got and adds a lot of LEDs. It's a blinkenlight project for diagnostic usage.

C64-Lumafix

An easier to solder version of the Lumafix board, components spaced out a bit more to make things easier on the beginner (mostly meaning me). Can also be used to bypass noisy signals on motherboard, wireing directly to modulator replacement.

BulkyMIDI-32

A HW build of the MT32-PI project, allowing you to emulate a Roland MT-32 using a Raspberry Pi. Includes enough additional modules to build a MIDI-mountain as well as adapters for connecting to most things retro.

C++

C64-Power-Saver

C64 power supplies are ancient, they go bad every day so use protection!

C64-Pi1541-Module

I wanted an alternative to the SD2IEC on my Commodore 64, and I almost instantly took a liking to Pi1541 software. I did however need to design a board for it and this was the end result - even includes beepers, OLEDs and two IEC connectors

C64-XUM1541-II

An updated version of my C64 XUM1541, this supports the newer XUM1541 firmware and comes with a few extra goodies.

Batchfile

C64-XUM1541

Simple PCB for building a XUM1541, a device for copying data to and from Commodore 1541 disk drives using a modern computer.

Batchfile

Amiga-DrawBridge

A PCB build of Rob Smiths Amiga DrawBridge, an Arduino-based solution for reading and writing Amiga floppy disks on modern hardware. Also includes version of Greaseweazle.

RC1802-Cosmac-ELF

With the RC6502-project for making an Apple 1 replica done I wanted to do something different, so I started designing a simple version of the RCA 1802-based Cosmac ELF instead.

C64-Kernal-Switcher

Switchless kernal switcher for the common breadbin Commodore 64, "longboards". Reuses power LED for easier use.

C64-CPM-Cartridge

A recreation of the CP/M cartridge for the Commodore 64.

8BIT-Wave

An Arduino-based tape player for old school computers like the ZX Spectrum, Dragon 32 etc. Hardware is compatible with tzxduino/arduitape and Maxduino firmware.

C++

ZX-Interface-2.021

An old-school remake of the ZX Interface 2 with some modern tweaks - mainly by integrating bank switching into the interface itself. Everything done with basic logic chips and components, no magic black boxes in sight.

Assembly

RC-ONE

A recreation of the MOS KIM-1 microcomputer, the start of the Commodore-line of computers. Complete with hex keypad, six digit displays and a lot of 8-bit fun!

C++

C64-JoyKEY

WASD-style joystick for vintage computers. With an added Arduino Pro Micro you can use it as a USB-keyboard, so if you wanted a DIY streamdeck or Macro-keyboard - then the C64 JoyKEY can do that as well.

C++

C64-Stereo-SID

There are many Stereo SID boards, but this one in mine... Add a second SID of the same type or newer substitutes for adding stereo audio to your system...

C64-Joystick-Switcher

Wanted a joystick switcher for my Commodore 64, so I built one by adapting C64 Mega Switcher for use with Atari-style joysticks. Supports secondary fire-button when using Sega Master System gamepads, even includes an auto-fire circuit.

Composite-Video-Amplifier

Used for composite modding Atari console systems such as the Atari 2600

C64-Mega-Switcher

Adapter for using Sega Mega Drive/Genesis controllers on a C64, with builtin port switcher so no more cable switching!

Apple2-Prototyping-Card

Prototyping card for developing new hardware for legacy Apple ][, //e and //gs computers.

C64-Joystick-Adapter

A simple device that allows the connection of two Commodore 64 joysticks to a modern computer over USB (using an Arduino Pro Micro). The overall goal is to be able to use vintage joysticks with emulators.

C++

C64-PlayOnTape

It's a tapuino, mostly because I wanted to build one. Uses an Arduino to load tapes on the good old Commodore 64.

RC2014

RC2014 expansion modules and scripts

KiCad Layout

retropie-dosbox-configure

Simple bash scripts that can be used to configure DOSBox games on RetroPie

Shell

A7800-Mega-Adapter

Adapter for using a wired Sega Mega Drive/Genesis controller on an Atari 7800.

Atari-Joystick-Tester

Simple joystick tester, can be used with the common Atari 9-pin joysticks and paddles (tested using multimeter).

MSX-Mega-Adapter

Adapter so that Sega Mega Drive (Sega Genesis in North America) gamepads can safely be used with the MSX line of computers.

C64-IRQ-LED

Changes Commodore 64 power LED so that it is green when I/O is used on system, reverts to red when done.

Apple2-Joystick-Adapter

Adapter that plugs into the Game I/O connector on the Apple //e motherboard to add support for Atari-style joysticks, cables can be routed to the back of the case for easy access.

breadboard

Created a simple PCB that can be used to transfer breadboard contents more directly to a PCB.

Amiga-Mouse-Switch

An attempt at building an automatic Amiga Mouse/Joystick switch (when used with Amiga port 1) - pushing the button changes the device connected. No more two-cable Merengue for me on the Amiga 500, forever more!

D32-Joystick-Adapter

Joystick adapter so that Atari-style joysticks can be used on the Dragon 32/64 and Radioshack CoCo line of computers.

VBA

RetroPanel

The missing piece for everyone who has a functional AT-system, but only ATX-cases. This adds a turbo-switch, a smart power switch and that highly desired Mhz-display (also a clock, because why not).

C++

NoiseMaker

Compact Flash, SD-cards and Gotek drives take the anger out of retro-computing, but at the cost of an oddly silent computer. This is an Arduino project to solve that in a way that should be easy for anyone to assemble.

C++

RC6802-Microchicken

Computer based on the Motorola 6802 processor, called RC6802 Microchicken as it's an adaption of the one found in a computer projects book by Daniel Metzger.

Assembly

CPC464-Joystick-Splitter

A simple joystick splitter for use with the Amstrad CPC 464 computer. This allows the use of two Atari-style joysticks on the computer, but note that as the computer does not have power on the connector - this will not work with joysticks that have autofire.

Profile repository

A2600-Keyboard

A new version of the classic Atari 2600 Keyboard controller, mostly because I wanted the overlays without paying for worn cardboard sheets.

RetroShield1802-PCB

Arduino Mega 2560 shield adding secondary 1802 processor to run the latest 1802-based software (most may be from the 70s).

VU-Switch

Building an audio input switcher, four 3.5mm audio inputs and one 3.5mm audio output for connecting to my 80s Boombox. VU-meters added, because they're cool!

Acorn-Joystick-Adapter

Joystick adapter that allows you to use common Atari-style joysticks (C64/Amiga/Atari) on your BBC Micro computer!

Christmas-2020

A simple and quite fun Arduino-project for Christmas 2020 (it's a blinking tree).

C++

RC-Project-Board

Playing around with an Arduino and a breadboard is a lot of fun, but I wanted to include my retro-computer builds so I made the project boards to make this a lot easier (for me). Also includes a few projects, some of them in the form of PCBs as well!
