No way I’ll get to build them this year but I might eventually give in and try them. Especially reading how much hell @alenppc has had with the connectors. Would probably be an alenppc/superduper only license at this point.

Beautiful!, looks like a worthy compliment for a well travelled, heavily taxed A1200 expansion connector! :)

Out of interest, what were the main challenges in adapting the CD32 360 design to the 1200 from a logic point of view?

I've no idea. I've not figured it out/done it yet.

I guess this is the bit people dont get. Making the board is kinda easy. Making it work is hard and takes time. There are literally thousands of hours people dont see that i have put into these boards. And thats why when people start shouting at me demanding shit i tell them to f*ck off.

They look awesome!!

Will you sell the boards bare/empty?
I'd frame it and put it on the wall!!

May I ask how long would you estimate time spent on TF330 or TF360?

In general A1200 cards are quite pretty.
Edu board based on tf330 visually look great as well.

I suppose I was just under the impression that board layout / component choice / signal selection went hand in hand with the firmware development and that once you got to the point of actually ordering a PCB 90% of that work must have already been done.

Thinking about it further it makes sense that until you have a built prototype PCB to test then there's only so much you can do and that a lot of tuning work remains.

Where did this come from? I wasn't even aware that it existed.

This was prototype.
