MOS 8501 CPU replacement
Mantione Oct 31,2023
The 6502to8501 is a device that allows you to use a 6502 CPU in your Commodore TED series computer, it allows you to bring a dead computer back to life. The 8501 CPU in Commodore TED computers has an extremely high failure rate and therefore, replacements are often a necessity to use these classic computers. The device is an adapter that interfaces a 6502 to the 8501 signals with 74xx bus transceivers in between in order to implement the AEC funcitonality. Also, the CPU port is implemented with ...

DIY 5 buttons joystick for Commodore 64 - Vic20 / Amiga + autofire
Cristaldi Oct 23,2023
Since many, many years, a 3 button joystick for C64 is well known, but unfortunately not very widespread. Only the C64GS had some games which officially supported a second joystick button, and since the C64GS came out very late in the C64's lifespan, it never became common. Standard joystick ports on C64 (and Vic20) has the necessary hardware for 3 fire buttons, using the standard fire and the two connections POTX and POTY. This simple project adds two more buttons that uses two additional logic...

Commodore PET N type keycaps
Fachat Oct 15,2023
I re-build Commodore PET computers with new parts. Among the new parts are keyboards using modern MX-compatible Switches, and I needed proper keycaps for those.So, I created all keycap parts, and integrated them in the Tinkercad web tool.The key form is created using OpenSCAD by a parametric generator (by Thingieverse user rsheldiii, published under the CC BY-SA 3.0 license).Most of the top character prints are made from a Microgramm font, converted to SVG using the Font Squirrel web page.Some t...

Pi1541 option B hat for Raspberry Pi Zero with datassette IO support
Alexander Martinelle Oct 12,2023
Pi1541 option B hat for Raspberry Pi Zero with datassette IO support.The hat uses the option B schematics but with one extra tweak, the i2cBusMaster setting should be zero since it uses pin 27 for SDA, and pin 28 for SCL.The hat has an additional level shifter compared to a normal option B hat that can be used with a special kernel image that supports emulating the Commodore datassette: https://github.com/AlexMartinelle/Pi1541DatassetteSupport/The gerbers are available at: https://github.com/Ale...

C64 Pi1541-III Module
Lunde Sep 03,2023
The Commodore 64 was central to many a young boys childhood, especially those older than 30! Still, the community around the computer is alive and vibrant with both ideas and new solutions for using the old computer. The old 5.25" floppies we used with them on the other hand are nearing their expected lifespan, they simply were not meant to live this long so in order to keep loading our software and even back the old disks up to newer solutions were needed.Enter the Pi1541, a piece of software t...
