Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Speaking for myself, I love it when someone posts a pic of one of my pcb designs that they've built (or have been playing with! Like sawing a Gemini board in half to make a single Pico platform. :) ). I design them for fun and for people to play with.

I design my boards on lined paper. remember that. ok it's strip board but suits me.
I don't know why the olimex board is supported so much in mmbasic but there must be a reason like it works with 2350/pico2. it's cool.
an olimex board but vga socket with more wires could there be other vga modes, not hdmi?

Hey Stan, I have some of that proto-board stuff going on and SL6 is also great for this. Make mods and all you have to do is save as.

I love SL6. You can use it for all sorts of stuff. :)
Want to try a temporary change? Copy the whole tab and dive in. It it doesn't work then just delete that tab.

The Olimex board is well supported because it's fairly cheap and gives easy access to the HDMI connector. It was originally designed to run an original Pico with a DVI output - something that wasn't really practical if you wanted a BASIC interpreter and some user space too. It just so happens that the Pico 2 is a direct replacement so it works on that board.

Count them - it only uses 2 more pins for DVI than it does for VGA. You are getting a much nicer display system for that. :) It's even backward-compatible so that VGA programs run on it.
