The bit about how the AMD Athlon (K7) uses the same bus, and how they planned to make Slot A Alphas where the only adjustment an Althon motherboard would need is a different BIOS. Imagine what might have been, especially as Alpha Windows 2000 had a built in FX!32. Cheap Alpha systems with a good x86 compatibility story, it could've been a contender.
(Yeah, I know, several stars would've had to align for it to actually work).
There was a problem with that idea, DEC engineers working for AMD made K7 too fast for Alpha to compete.
"Cheap" and "Alpha" would have been hard to pull of simultaneously. But it would have been really cool.
