A572 clone (2MB RAM for A570 CD-ROM)

dalek · 15 May 2019, 15:10

I've copied the schematics in to KiCAD and produced and tested some boards for the A570 2MB RAM expansion (since I struggled to get hold of one, and there were no gerbers around the place).

I suck at PCB layout so some improvements can be made there, but it all works

Looks great! Always nice to see KiCAD designs. It's really improving in the last few versions.

Routing is much nicer on yours, thanks!

When I first started on this while all the info was out there, there were no gerbers that I could actually get. That's well and truly fixed now
