Performance 32x Memory Card

This is a much more engineered version of the memory card, utilzing a lot more electronics, and two 7 segment displays to show what card you're on.

Switching between cards if done by the "largest" dot which is the only button on it, it can be clicked to go to the next, or held to scroll through and release when it reaches which number is desired. After a new number is selected it will display "--" as it loads the saved memory into the SRAM chip.

Board

The main storage of this is unknown at this point, it utilizes two custom Datel silicon chips, one is an ASIC. It has an SRAM, shift registers, and a microcontroller
