Cool, That's much more compact than my dual board.
You're free to have it (I'll put it up on github, though until I can
recreate enough of the 8085 signals, it might not be as useful as the
below).
I will caution you that the busses and signals on the processors may
not be tri state; in my design I fully buffered every CPU signal. I
would have to check my notes as to which signals I found would be
problems.

Thankfully, The 8085 datasheet notes that Address, Data, IO/M, !RD, !WR,
are tristated, so I did not try to buffer them. Others might be
tristated, but the DS did not say for sure (It said ALE is NOT, so it
must be buffered).
