(DIY) CASSETTE PORT DONGLE for C64 586220 DIAGNOSTIC CARTRIDGE
C64iSTANBUL Dec 04,2020
(DIY) CASSETTE PORT DONGLE for Commodore-64586220 DIAGNOSTIC CARTRIDGEHello,The 586220 diagnostic cartridge is a very popular Comodore-64 diagnostic tool. It can test many functions of your Commodore-64 and find if there is a fault. Previously I shared a PCB to make a 586220 diagnostic cartridge.But the 586220 diagnostic cartridge is not enough for testing everything, you need some extra connections (dongles) for testing input/output ports.I have prepared some simple dongles to test the input / ...

TapeXUM - Capture and write Commodore tapes via USB device
rime / Fancy Rats Dec 03,2020
What's TapeXUM ?TapeXUM is a USB device that can read and write to cassettes of Commodore 16/64/VIC-20 (read and write) and ZX Spectrum (read only) format. It requires a Commodore datasette connected to it. This project is based on ZoomTape by Arnd Menge, a great idea and originally a part of OpenCBM package. TapeXUM uses Arduino Pro Micro and through hole components so it's a DIY friendly design.Huge thanks to Data/Tropyx for creating enclosure design for 3D printing!Download firmware for the A...

Amiga Dual Drive Adapter Board (DDA)
Stuart Hudson Dec 01,2020
I have designed a small PCB to give Commodore Amiga 500/600 and 1200 users the capability to have both Floppy drive and Gotek internally while also having a CF installed. This get's rid of any external ribbons and connections. Giving the Amiga a OEM look and giving the user all media options! There is a guide video on my YouTube channel SHG Retro at: https://www.youtube.com/watch?v=1tK1ZH_6ZOc

L1 filter replacement for Commodore C64 BN/E 250469
Per Olofsson Nov 27,2020
The original L1 line filter for the 250469 boards, possibly a Tokin D-08C2, is out of production. This adapter board lets you use the modern Laird CM4545Z131B-10 as a replacement.

Commodore 64 IRQ LED
Lunde Nov 22,2020
Wouldn't it be nice if your fancy old breadbin-styled Commodore 64 computer could tell you more about what it is doing? Well, now you can have the power LED change to green when it is performing I/O operations (IRQ-line is being used). Amazing stuff, it really needs to be seen to believed so get yours now! Not really necessary though, it is however a fun modification to do with just a handful of parts!Check out the github-repository for BOM and instructions.

Commodore C64C - 4x Kernal switcher with Restore
Giu MacGyver Nov 21,2020
This project allows to replace the original C64C (new model) Kernal ROM, with 4 different (special or customized) Kernals selectable by the Restore Key, using just one 64Kb memory chip. No external switches are needed. Just extract the original Kernal (by desoldering or removing it, if it is provided with a socket) and insert this Adapter 4xSwitcher. Connect RESTORE and RESET signal to the MB and you're done !
