Title: Building a Gameboy Oscilloscope
Post by: Keoni29 on July 01, 2015, 02:01:09 PM
I recently picked up an incomplete electronics kit for making a Gameboy oscilloscope cartridge. The kit contained an unpopulated circuitboard, some random chips and a diskette with link software.

Apparently this kit was published by an electronics magazine. This is the article that went with it:

I almost have all the required parts for it except for some rare chips. Here are some pictures:

Whoa, thats awesome :o. It would be cool if something simmilar could be made for a TI-84 :3 though i guess 2 bits on the IO port is to inaccurate :P

That is not the point. The cartridge contains all hardware for converting the analog signals to digital. The z80 inside the gameboy then reads the digital information and puts it on the screen. With a calculator linkport you're limited to a 2 wire interface. You CAN read digital data from an analog to digital converter using just 2 wires, but it would be way too slow for realtime measurements like on an oscilloscope.

I would like to see a Game Boy oscilloscope into action. Good luck Keoni29 :)

Good luck!
What chips are you missing?
