Who turned the clock…?
Every CPU needs a clock to be able to work. The Commodore C64, however, has more than one of them. I try to explain the different clocks in this article.

Z80 Cartridge with 8MHz for Commodore C64
My well known 8MHz Z80 cartridge for the Commodore C64 in a cartridge compatible board format, smaller but just as powerful!
The EasyGate1541 now also for the 1541-II
The EasyGate1541 was previously only available for the “old” 1541. The later 1541-II got another gate array from Commodore, which has even more functionalities integrated. It was about time that an alternative was created.
3D models for PCB layout programs
Meanwhile many PCB layout programs are able to create wonderful 3D renderings of the PCBs. For my boards I draw all 3D models myself. And some of them I have already made available for download.
The ZX1541 interface for the friends of through-hole components
Building the ZX1541 interface in SMD was no problem, at least as far as the space required for the given board dimensions was concerned. It was a bit more tricky to realize the whole thing with THT components with unchanged dimensions. It wasn’t easy, but in the end it worked out.
