Subject: North* CPU Card -- help!

Hi All --

Can anybody help me with a North* question??  I acquired a North* cpu
recently for a few bucks.  I'd like to try it out, but have no dox.
The silk screen next to a 16-pin header says "POJ Address", which I
assume to be the power-on-jump vector.  The header is wired like this:

               +--------------------------+         /`
               |          /^\             |        /
               |  o--o--o/ o \o  o--o--o  |       /
               |   \___     \______    |  |    top right corner
               |       \           \   |  |     of card.
               |  o  o  o  o  o  o  o  o  |
            *  |                          |
               +--------------------------+

* is marked pin 1.  Where is this guy going to start up??  Why are there
three connections here??  The lower right two pins are ground, but pin #3
(?) doesn't appear to be +5.  Is that 0D000h??   Anything "funny" about
the North* Z80A cpu that I should know??  It's marked "ZPB 023513" and
 "ZPB-A ASSY 08014J S/N E-1-B"
