The next Tiny Tapeout "Tiny Tapeout 4" has been announced - if you missed TT03
and still want to have a go - check it out.
It has a new pin interface - 16/24 pins, some bidirectional, much faster
clocks. I'm planning on redoing my PDP-8 to use a full 12-bit interface - I'll
write things up for everyone when I've spent a bit of time with it.

If you missed out last time I'm happy to talk you through the process, come on
down to Makerspace on a Thursday night
