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.
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.
After I presented my last TriMod adapter prototype based on CPLD, I was asked if a version could be made that would fit into a closed 1541. So I optimized the whole thing a little bit and developed a PCB.
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.
I recently came across an interesting project. It was about a so-called EPROM emulator. So a device, which among other things via USB via an adapter pretends to be an EPROM.
