Hello, There is a software emulator for the Apple Newton PDA called Einstein, the developers are looking for documentation for a legacy chipset manufactured by Cirrus Logic to improve the emulator.

Would any of you happen to have a copy of the Cirrus Logic Voyager CL-PS7000 Apple Newton PCA Chip Set Engineering Specification?

Apologies for the talk of legacy closed hardware but it is about open source software if that makes it any better :) https://github.com/pguyot/Einstein
