A lot of boards (one of mine in fact) won't power the 5V (VBUS) over USB, and the keyboard needs that. Another one of my board does do this when I supply external power over the jack. If you have a USB breakout connector your could inject 5V.

gadgetjack said I am amazed at the code that comes out of these 3 smart men. Some great fun for all of us on the sweat of these guys and their code. I tip my hat to all three of you.

I am assisted by claude and codex. I am using 30 years of coding experience for design and architecture, but this would probably have taken me a year on my own.

Now you've got keyboard and a display - full computer!

I am working on a CYD (Cheap yellow board) port - which will just be an original ESP32 port. Probably a lot more limited, but I think it will work.

The port itself didn't take long. VGA is a bit of a heavy lift as the hardware is different the memory more constrained. The CYD LCD displays I think will be fairly standard, we'll see, I just ordered a few from amazon. So many dev boards... Some people do wood working, I collect dev boards.

You and me both. After I retired I started collecting lots of development boards from ebay and aliexpress. Every once in a while I get to use them for something neat, like game emulators or smart led marquee displays and such. Lot more fun than keeping factory lines running.

The trouble with them (apart from their tendency to breed) is that many are designed for C or Python breadboarding and tie up pins that MMBasic would like. Usually perfectly logical ones, nothing silly. Like why split the audio over two different PWM channels? Why put stuff like a UART in the middle of the HSTX so it can't be used? PSRAM has really messed things up - the perfect opportunity to put its enable pin in awkward positions...

Looking forward to the CYDmite. :) I've just ordered a third as I don't really want to wipe ASCII Aquarium yet. :)
