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.

LOL I posted this back on the 7th thinking is may be of use as its open source.

  And he showed a few other cards making use of the pico.

Hi All,

@Quazzie,
I didn't see your earlier post either.

I wonder why they used a Pico-W instead of a Pico?

Regards,

Mick

@ Mick - perhaps they only had a W on-hand.  As far as I can see from the video, they are not using the WiFi ability at all, so a standard Pico module would probably also work fine.

@ Plasmamac - Nice idea, but I don't know that that would ever work.  I expect the MMBASIC interpreter overhead would make it too slow to talk to the ISA bus, which I think runs at about 8MHz, so the Pico is PROBABLY using the PIO's and C to be able to talk to the PC ISA bus.  I may be wrong, but I don't think MMBASIC would be fast enough for this kind of task.
