These documents have been obtained from extensive searches on the net, as well as from my own personal collection. If you have any documents that you'd like added to the archive, please contact me.

This collection would not have been possible without the work done by: Al Kossow (bitsavers.org),

If there's anyone I've missed, spelled incorrectly, gave the wrong URL for, etc, please let me know and I'll update.
