The ALTOS server box I have has no 808x that I've seen so far, not that it's
been examined with any rigor. The second board is that 2900-based HDC I
once described.
The box is sort of squashed-hexagon-shaped, and the cigarette-stain-brown
doesn't wash off, so I suspect it's there by design.

I think the
