Kerberos is a MIDI interface for the C64 and C128 with integrated flash memory. With this cartridge for the expansion port you can connect MIDI devices like keyboards and synthesizer to your C64 or C128. The 2 MB integrated flash memory allows to save programs for quick start, which you can transfer over MIDI from a PC or Mac. The 128 kB integrated RAM can be used for programs as a memory extension. The cartridge provides an EasyFlash emulation as well, you can store an EasyFlash CRT image with up to 1 MB on it.
Pre-installed is a menu system to start the programs on flash and to flash new programs, and the following programs:
The project was successfully funded on Startnext (English page, German page). I plan to build more soon, you can follow me on Google Plus for announcements of it (and you'll get a few unrelated geeky posts), or subscribe the Kerberos MIDI Google Groups, where I'll announce it, too.
The program to upload PRG files to the flash, Kerberos App, is available for PC (Windows) and Mac (tested on Mac OS X Yosemite, but should work with older versions, too).
