Philips G7000 VideoPac / Odyssey2 cartridge case for EPROM mounted on original PCB

thingiverse

Replacing a bad ROM in a VideoPac cartridge with an EPROM using two IC sockets to keep both the PCB and the EPROM intact made the resulting cartridge too tall to fit into the original case. This simple holder for an original PCB allows you to insert and remove the PCB from the console without fully enclosing it, since the cartridge slot is too narrow for a lid. The design was based on the sockets and EPROM used to modify my VideoPac 22 "Space Monster" - your results may vary if there are differences in the PCBs. The case has been designed at its thickest point just slightly thicker than the EPROM to prevent it from catching the edge of the cartridge slot. The bottom is cut out to allow you to move the lower edge of the PCB forward after inserting it so that it can reach the PCB connector inside the machine. To use, simply insert the PCB, push the top back, and then insert the rest of the way. There is an edge over the PCB that partly obscures the EPROM from view and protects kid fingers, while also allowing you to mount additional components like switches if you want to experiment. The screw holes are designed for M4 screws but a Sketchup source file is included if you have shorter ones available.
