All I found on the net is a picture:

http://mylinuxisp.com/~jdbaker/oldsite/images/CardZ180.jpg

the resolution is not good enough to make out the details like the
chip part numbers, but some things can be guessed.

Looks like 32 chips on the left are 1 MB of DRAM. The 2 vertical chips
next to them must be address multiplexers. This leaves very few 
unknowns. The 2 chips next to the slot connector are likely PALs
implementing the interface with the Apple slot.

The bottom line is that if the programming model is found, the 
complexity of making a functional equivalent is no higher than that
of making an Applicard clone.

"Based on the design of the venerable PCPI AppliCard". Likely a similar
Apple interface with a different MMU using the z180's native memory 
management.
