Here is an German version [German] !
This project includes a parallel cable set for the Commodore 1541 disk drives of types 1541-I, 1541C, and 1541-II. The basis of the project comes from Sven Petersen's parallel cable project on GitHub. The set is compatible with SpeedDOS and DolphinDOS2. However, I adapted the circuit board for my 8x switchless multi-speeder project, allowing the operation of DolphinDOS3 in addition to SpeedDOS and DolphinDOS2. The set works even without the multi-speeder.
This repository includes the Gerber and BOM files.
