Seems somewhat less optimistic than the notes on the main page of your repo :

Experience always trumps early optimism. ;)

But well spotted.

Does anyone have the PiStorm PCB schematic in KiCad format?

I'm looking at rolling my own board design.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Thought it was in kicad format ? Though I don't remember offhand where the repo was.

Edit:
Can't see any PCB files other than @Badwolf repo for the ste https://github.com/dh219/pistorm/tree/w ... istorm-ste

I recreated the schematic for PiStormSTE from the PDF.

It's only got a few things added (and the second regulator for the other CPLD type removed). You should be able to use it as a basis for a refactored DIP PiStorm too.

Thanks. I've got it open. I just have to work out how your wires work as you seem to have used nets rather than labels.

Labels assign nets in KiCAD, I thought. ie. there's no distinction AFAICT.

I've not used global labels, if that's what you mean. It's a single sheet design.

Oh I see! I usually use global labels as they're global (on the one sheet :-) ).

So many ways to skin a cat.
