Proof of Concept Altera DE1 Expansion Board (update)

Last week I was thinking about a schematic that I’ve seen on Caro’s website for connecting Joystickports, a keyboard port, Audio out, CAS and slot connectors on an Altera DE1.

I’ve worked this out in a proof of concept just to see how it looks.


The idea is to place the connectors like this.

Also I’ve got the idea to put Slot1 in a angled possition, so it’s possible to use big cartrides or a slotexpander, without blocking slot 2.

Current status is, that it’s just a Concept but please share your ideas in the comments.
