Even cooler that you know all about it :-).

SN 1245, Rev 3.0. There's a handwritten "O" before the "CBD-X31"
designation on the board.

In that case, would anyone else on the list want to grab it?

The RL11 and RX211 both date from 1978 or so and do DMA from a single Unibus
slot. Seeing how the date on this 68000 board is 1982, does this mean that
a predecessor to this board was being made in 1978 or earlier?
