Joe has put an incredible amount of work into this project. As such, he would like to share with the community his progress up to this point. The schematics themselves are not complete and not ready for prime-time. But they are very close barring a few unanswered questions I hope we can resolve this week or soon thereafter.
Behold! From Joe on the making of new schematics:
The KiCAD software creates the 3D model from the board layout automatically, so the 3D render is a nice feature that doesn’t require any additional work other than downloading the models for each part.
This is simply a herculean effort and a non-trivial amount of work and love has gone into this project thus far. I've been trying hard to keep my personal emotions out of this. But you guys, this is starting to feel real. My level of excitement is definitely starting to turn up a few notches.The "x-ray" is the actual board design I put together in KiCAD. Each color represents a layer on the 4 layer board. I forgot to un-hide one of the layers before taking the screenshot— it’s missing the yellow, layer 2, so there’s actually many additional traces you can’t see there.
In addition to Joe's brilliant efforts, SEA-CCC.org member Christian has built some adapters for the RAM. This will allow the use of much more common and accessible RAM chips as well as bump those with the correct Agnus up to 2MB. We will be testing these adapters tomorrow (October 3, 2018) and discuss next steps for reading the logic on the PAL chips. Progress! Good times my friends.
