Can’t wait to see it!! I’m sure you will post pics of the blank PCB the moment you get them. If you don’t… shame on you!!

Oh don't worry, you can rest assured the very first thing I will be doing once they are ou the packet is posting a picture on hereCan’t wait to see it!! I’m sure you will post pics of the blank PCB the moment you get them. If you don’t… shame on you!!
Whoops, forgot that one......Oh don't worry, you can rest assured the very first thing I will be doing once they are ou the packet is posting a picture on here
However, I can now post a picture of a fully assembled V1.2 board:
The good news is that it works just fine! No patch wires and no weird NVRAM issues
So the LC board currently has no schematics available, I thought it's about time that changes!
This is going to take ages.... I have got used to how easy it is to work in sprint, going back to using KiCad is kind of painful. That single simple page took a few hours to draw (And I just noticed I missed the label on BERR) and I didn't even make the 68020 symbol form scratch (it's a modified version of the PGA symbol from Sakura-IT available here) I hate to think how long the symbol for the V8 will take to make!
If this turns out well I'll look at making new schematics for the Plus, LC II and LC III too

And we have schematics!
I have literally just finished drawing these and have not extensively checked over them so there will likely be errors (If you do find any let me know and I'll fix them )

Board layout files, as well the the KiCad files for the schematic are now available
