Score! It'll take me a while to digest it, but that's some good depth
of detail you've found. From the most ground-zero source, no less.

Thanks to all who've contributed to this thread, I'm grateful for your
support. I'm going to bungie back off the list again (traffic is a bit
high-volume for my current attention budget) but maybe I'll see some
of you at the Vintage Computer Festival or California Extreme in a
week. I'll be the long-hair wearing a black "Gauntlet: Dark Legacy" T
and/or a gray Atari vest.
