[Coco] How SLENB works ?

[Luis Antoniosi (CoCoDemus)]

Well actually none of them can emulate a coco-3 and they don't have video
output. Better go for a rasp Pi fo this task.


What i'm doing is trying to emulate devices, like rom, drives, etc.

I started ordering the arduino mega, but it's too slow maybe for those
purposes and I will have to move to the arduino DUE. But keep in mind the
DUE needs to be level shifted to 3.3v on ALL PINS!
