Ah HA! I see it now George! The two edge connectors at the left & right
edge of the board (as it faces us) are indeed the power and gnd connections
for the Multibus. The board plugs into the P1 slot with those two 6-finger
edge conns. How dumb of me not to realize this.
Man, I was looking at it from the upper edge conn. being the part to plug
into the Multibus P2 connector but I was wondering how in the heck the
sides of that upper edge would clear the card rack and backplane! I was
thinking those 6-finger connectors were just used for I/O or something. The
shape of the board is not what I'm used to seeing for Multibus boards (I've
got a dozen or so of the 'traditional' style around here of various types.)
Apparently I/O was handled through that edge conn. at the top of the
picture, true?
Thanks for this bit of info that might help me when hunting through a pile
of boards at a hamfest, etc.
Regards, Chris
