Ah... I hadn't realized that. I assumed it was a 22-slot backplane from an
IMSAI 8080 - I was going to pull apart the IMSAI and check the number...
Both of my 8800's have 12 slots installed, so I could still use the board,
although chances are I wouldn't actually install it (neither Altair is full,
and 16 slots would be pushing it anyway for the 8800's power supply). Let
me know what you want for it, and if reasonable, and nobody else has a better
use we can talk further.
[I suppose with the front-panel, and the right cards (CPU, 64K RAM, disk and
serial I/O in three cards) I could build a "very short" IMSAI with it - it
would even be kinds cute]
