Hi Ernest.
Some fiddling around and everything seems fine until I put ROM I in (IC 27, the one that contains the menu ROM)
With ROM I in, it seems... erratic? It'll sometimes boot me to the menu but no keys work. Sometimes I get the top row filled with characters.
Without ROM I, it boots fine to the Applied Technology BASIC Prompt.
This is a long shot, but could it be something to do with C29? I'm using a switchmode power supply and it still has the normal 4700uF capacitor in there.
(Not sure what impact it would have. It's just a smoothing cap)
Cheers!
John
