Back in July '15, Ben did a console brain surgery between a Sega Master System and a Colecovision, but didn't do 2 things:
1) Adding a third system (CP/M computer? Sega Game Gear?), and;
2) Actually finishing the console by adding a case and making a complete "product".
This time he could tackle that and, hopefully, make an actual PCB, maybe through some manufacturer, but designed in EAGLE by Ben.
And it's absolutely alright if this project takes more than one episode, as long as in the end he has a complete enclosed unit.
It's time for it, Ben Heckendorn! Finish Himmm!... It! Finish it!
