I'd say you got the CPU-board of a system that normally
has a pasive ISA-backplane ......

I've seen these in XT systems but not yet in a 286 issue
(Headstart comes to mind) but given that Kaypro generally
made luggable systems a deviating formfactor could be

I would not put it into a normal mobo's ISA slot because
if it is intended for a pasive backplane lot's of things
could go wrong .....................

The 4way connector with 2 middle leads cut out sounds
like the speaker-connector.
