Actually I don't think that's right... looking at the pins outs... https://www.exxosforum.co.uk/forum/viewt ... 1146#p9335

Pin 8 would simply be left not connected (its gnd), but it picks up gnd from pin 1 anyway, so the connector would still plug right in anyway..

Well done to you as well. Points for resistor stripe alignments. One problem I see. And it's a big one...

...you're not using a BAD DMA!

And I finally join the select few with a board that's ready to go.

Got bored of soldering, so will put the other ports in once we get the whole thing up and running.

So, now it's down to who dares to go first? :D

p.s. whats the jumper near the rom for?

Welcome to the fold Forgottenmyname.

I won’t be able to switch on till Sunday.

I think whoever turns on first should make a video of when you flick the switch so we can all see what happens.
