Yea, I am using this computer for my senior project.  The computer uses the
8085 which real close to the Z80 I hear.  The assembly language is 
simple and straighforward.  The computer also uses the 8155 to do a lot of
its peripheral interfacing.

Recommendation:  Go to Radio Shack and order the technical reference manual. 
It -is- available.  The tech manual has EVERYTHING you need.  You will see
that it is simple to interface with the bus since that access is provided
under the back pannel.
