Open Hardware Fast Loader cartridge for the Commodore 64 and 128 - DO NOT USE!!!
I learned about the existance of this cartridge when my friend Terje suggest me to watch this video by Adrian: it outperformed JiffyDOS, so I started to look around for information. This way I found out that it's the only cartridge of its kind to have native support for the Commodore 128 and I even found the original schematics (including the PCB layout!) in the manual. So I just decided to remake it.
