I recently uploaded as much of the original design specifications, schematics, and logic coding as I could find up onto the HexBus and Datasheets & Manuals folders on WHTech. As of now, about 90% of all TI documentation for the 99/8 that was ever produced is up on the site. The current hoard came to me straight from the hands of one of the original 99/8 engineers.

Bill/Curtis, the HexBus stuff pretty much completes the set--I'm pretty sure everything they ever did for it is up there now.
