I also obtained the IP from Bob for these boards. I understood the
difficulty trying to obtain the original parts. It was my desire to
move to a newer device for the XC9536XL. I have both the Z80 and the
8080 boards from Bob. He had also suggested some added functionality.
If we keep messing with 8080- and 8085-based boards here, an ICE might
be something we want to pursue.
I used Bob's 8080-ICE to find some problems with some MDS-800 CPUs for
Richard, at one point several years ago.
