Project cartridge
Posted: Sat Oct 28, 2017 7:28 pm
Hi everybody,
I have a simple work in progress project : re-create a game cartridge. My goal for this project is to understand more how works the memory map works and how two eeprom chips can be used on a single board.
Also, it's a nice way for me to increase my Eagle designing skills 
I am already working on the PCB, and I am planning to 3d-print a game case after drawing a 3D CAD model. I should have all the hardware (UV chips and programmer device) to burn the 4k uvproms.
I just have two questions : First, I don't understand how to deal with the ROM files and the two chips.... How can I split the ROM file and convert it into a HEX ? I just have to manually cut the file in two ?
Other question : I am looking the the exact PCB edge connector part design. I know that the pitch is 2.54, but I'm not sure about the pad width. Didn't know if this design is a standard ? I see that some pads are wider than the other one (the 5v and GND signal) but I was looking for an accurate value.
My design is the 2*4k PCB (I have a physical one, it helps me a lot...)
Thanks !
Pictures soon...!
