This is a GTAC-2 type Apple clone, nothing unusual. Here in Germany 
these were sold in almost any electronics store in the late 80es. This 
board does not have slot 0+4 because 16k and Z80 card are included.

The small card with the two EPROM chips goes into the "slot 0" position. 
 It contains regular Apple II+ firmware. IIRC the 2764 is $Dxxx/Exxx 
and the 2732 holds $Fxxx with the Monitor. There is a 3rd /CS line so 
you can fit three 2732 as well. The fourth socket is not used, only data 
and address lines are connected.

As mentioned elsewhere, you should put the Z80's /RD pin back into its 
socket and take the opportunity to check the other ICs as well. Maybe 
somebody removed a chip during a repair attempt and put it into the 
socket backwards.
