Mac PALs

My original pages were eliminated in 2009, but I have a mirror: http://www.merlintec.com/lsi/mac512.html When I fixed a broken link to this on a Wikipedia page (a Talk page, not even an article) I got banned for life for "spamming". Which is funny since you can't get from the mirror to the main site without manually editing the URL. In the original 2005 discussion, I remember someone saying they had obtained a copy of all the PALs from Apple as part of a maintenance contract back in 1985 or so. And then he published the sources (or mailed them in private to someone else who then published them). I can't find any trace of that now. Like I said before, I looked at all this material but didn't make a copy of it. I didn't program the PALs, the Unitron people did. And if they protected the ones in the machine that Alexandre has, it is almost certain to be the case for the one I have as well. On a related issue, one of the owners of Unitron has claimed in two separate interviews that they had 300 machines in a warehouse. I really, really doubt this (though 300 cases instead of whole machines might be possible). When I turned in my design to Unitron in late 1987, Alberto told me "We tried your equations on all the machines we have and out of the 30 about half didn't have sound". The project was killed in practice soon after that and I doubt that they built more than a couple of extra machines as part of the Mac 1024 project. But there are some people out there waiting for those 300 clones to turn up some day... -- Jecel
