A collection of cartridges, adapters and replacements for the Commodore C64.
- DiskBuddy64 is a minimal adapter that can interface a Commodore 1541(II) floppy disk drive to your PC via USB in order to read from and write on disks. It uses its own fast loader.
- TapeBuddy64 is a simple and inexpensive adapter that can interface a Commodore Datasette to your PC via USB in order to read from and write on tapes.
- SD2IEC LP is a C64 SD-card adapter and floppy disk drive emulator based on the design by Lars Pontoppidan with cassette port plug. Copy C64 games and programs to SD-card on your PC, put the SD-card in your SD2IEC and load games and programs on your C64!
- Tapuino is a Commodore Datasette emulator based on the design and firmware by Sweetlilmre. Put your TAP-files on an SD-Card and plug the device in your good old Commodore!
- The classic xu1541 is a Commodore floppy disk drive to USB adapter based on the designs by Till Harbaum and Spiro R. Trikaliotis. It connects a variety of CBM drives (1541, 1541-II, 1570, 1571, 1581, SX-64's internal floppy disk) to USB-equipped PCs running Windows, Linux or Mac OS X. This allows for easy transfer of disk images to and from these devices and helps you preserve your old data.
- TapeDump64 is a simple and inexpensive adapter that can interface a Commodore Datasette to your PC via USB in order to dump your old software saved on tapes as TAP files. It is inspired by TrueTape64, a similar project by Francesco Vannini.
- A C64 keyboard to USB adapter based on the design and firmware by Mikkel Holm Olsen. Use the original keyboard with you favourite emulator!
- The SwinSID nano is a replacement board for the legendary SID soundchip of the Commodore C64 based on the design by Swinkels.
- A simple 8k cartridge for C64.
- A MagicDesk compatible cartridge for Commodore C64 based on the work of Marko Šolajić and Zzarko. Build your own cartridges out of multiple PRG-files! Has a 64k variant and a 256k variant.
- A 512k MagicDesk compatible cartridge for Commodore C64 based on the work of Marko Šolajić and Zzarko. Build your own cartridges out of even more PRG-files!
- The FreeLoad cartridge is a simple clone of an Epyx Fastload cartridge, offering a system reset button, a file access activity LED and a disable switch. Load 5x faster from your floppy disk drive, your SD2IEC or your Pi1541!
Eagle library for USB connectors printed directly on PCB.
USBQ is a Python-based programming framework for monitoring and modifying USB communications. Uses the kernel module from USBiquitous to implement the MITM part in the USB stack. Really does need an external device to actually sit in between the device and the system to sniff the data. Hmm.
This is the PSU board for all your retro modding needs like making a GameBoy Zero with any of the Raspberry Pi products and it’s Clones like Orange Pi, Banana Pi etc, it has even powered Robots. This board has all the features the modding community wants and needs for their build into a small and powerful package. Outputs up to 6A @ 5.20v. i2c enabled, so the power cells can be monitored.
This module implements a serial-level interface to the inexpensive USB-enabled geiger counters (available on Amazon) manufactured (or probably OEM'd, based upon how their docs read) by GMC. Does most of the fiddly stuff automagickally so you spend more time pulling data out of your sensor than you do figuring out how to pull data out.
Human Interface Device emulator for NFC readers. Reads the chip, outputs the contents as if it were a keyboard. Designed to run as a service in the background (or more accurately, a user daemon - since it requires the current user desktop session to function). The ideal time to start the program is on login. To avoid conflicts, the application will only attempt to load once. You may have problems getting it to work after switching users unless the first user logs out completely.
Requires pcscd, Python v2.7.
A boot floppy image that can be used for booting weird or recalcitrant machines from other devices, such as CD-ROMs.
Or, "You have LVM running on one box and an external drive, also running LVM, with the same volume group name - how in the hell do I mount the external drive?!"
