[NTLK] Newton ROM card circuit board files reverse engineered

[Matthias Melcher]

Not much happened in hardware in a while? Well, here is the complete ROM circuit board reverse engineered and put into an Eagle PCB and (still to be cleaned up) schematics file. Some additional findings in the text.

This is the card I am talking about:

The PCB, ready to send to manufacturing (if anyone ever wanted to)

What is the practical application? Well, we can add 8MB of internal flash with this board, and create new and improved ROM images that include the Y10k fix, for example, or just have fun understanding PCBs ;-)
