@timixretroplays Just found this on AliExpress - thanks! - and each board is SEVENTY FIVE UK PENCE WITH FREE SHIPPING. I’m building my #transputer emulation system with Pi Picos, and if I can get PIO working off something this small, I’ll be able to build a cluster for next to nothing! Incredible!
So I have the USB CDC link to debug, then integrate the slow GPIO link, and get the separate link adapter build working.
Then it’s time to get it all building on all platforms - with some extra IServer code for Windows ‘cos serial I/O is a completely different beast on the Fischer-Price OS (of course it is, blessss…)
And I’m maxed out with other stuff involving different hats… so I’m not setting deadlines, other than “the future” :)
I _think_ this means my soldering is OK and it’s working! #transputer

Got my first transputer program running from my #PC6502
Very simple code that spits out 0xAA000000 if it’s a 16 bit transputer and 0xAAAA0000 if it’s 32 bit.
Output is -
<< READ =$AA
<< READ =$AA
<< READ =$00
<< READ =$00
Next write something simple to confirm the tool chain I have works.
Then a server program to run on the 6502, so I can then run some Mandelbrot code on the transputer.
Long way to go, but fun
