Just in case anyone's interested, I've finally gotten around to cleaning up the PERQemu source to the point where Idon't feel too ashamed to show it to others. (It's still a bit messy.) I meant to do this years ago but kept putting it off. I'm releasing it under the GPLv3 in the hopes that maybe some other PERQ fanatic can finish what I started (or at least use it as the basis for a different implementation). These days I have too many other projects occupying my time to spend much time with it, and I kind of got burned out on it a few years back. http://yahozna.dyndns.org/projects/PERQemu/source/PERQemu-source.zip (And you can read more about the project at http://yahozna.dyndns.org/projects/PERQemu/index.html) And a big thanks goes out to our own Tony Duell for his extremely patient help with this project; the answers he provided to my questions when I started on this project back in 2006 could fill a small book :). And thanks to Al & Bitsavers for the scanned documentation and archived software. Without these this project never would have gotten started. Thanks, Josh
