Let me know the # of pins, pin spacing, and package width, and I'll
add the chip to the CAD program....

If you do want to pursue this project (making a mockingboard)Or any
other
apple II hardware project, let me know!  I can make 2 sided drilled
Printed Circuit Boards using a REAL APPLE II!

I just got done printing an A/D board and it works good!  I had to
file
a bit on the BUS connector, but it fits and functions.  I need to find
some plating chemicals!  The card fits in the Apple II slot and the
case cover fits nicely

The mockingboard is a very simple design.  The traces go from
the bus connector, in a straight line, to the chips.  Very
easy to trace by sight.
