Pi1541 Zero & Epyx Fastload Cartridge (PCB Way) Extended w/Rotary

thingiverse

I wanted to have a rotary controller added to my PCB-Way-based Pi1541 Zero (links to the original project in the projects here that this remixes), but I had a few additional changes I wanted to make; - Space for the rotary encoder - top should be angled upwards so it could be easily read when using the computer - space for toggle switch to enable/disable the ROM (see below for more info) - I wanted the activity light to be more visible - slightly more space for a socketed ROM So the changes I made to the original designs are: - I tented up the top to angle the display - tenting the top also gives enough space for the rotary encoder board (put the pin header at the top) - button bracket for the back to extend the two unused pushbuttons to the back panel - small bracket to hold a 7x7mm square pushbutton toggle switch to enable/disable the rom - activity light is to be mounted top and center on the cart. (extend it with wires) Enable/Disable of the ROM is accomplished by cutting the trace coming from pin 9 on the cartridge connector, and then having each side of that trace going to the switch. My C128 boots to C64 if the fastrom is enabled, so I wanted to have a way to disable it, so i can use the Pi1541Z in C128 mode. (I'll add more photos to this project shortly, showing the internals of my built unit.) If you only want the tented rotary top part, then you can use "Pi1541_rotary-short.stl" with the bottom from the original project. I also provide "Pi1541_rotary-knob.stl" which is a matching knob to print for it. The exploded view above shows how the switch bracket/guides are to be aligned. It should all just stay in the correct location once screwed together and assembled.
