I have managed to aquire a copy of the PowerMac developers notes. Should anyone want this i'll gladly exchange it for any interesting CD-ROM, these notes contain all the PowerMac ( just under 100 A4 pages) information you'll ever need. I'd give it to you for free if I had a soft copy.
If you just want some detailed info simply ask your question in the readers corner next month. I'll be happy to answer it if I can.
