I could have plugged them all into the board at the same time which
pretty much obliterates the board which was how we had to work, it makes
a pretty pile though. Add a can of freeze spray and the occasional
cooking chip smell and you have what we worked with on half the run-up
to CES Essentially every custom chip had a tower except the 8563 which
just plain didn't work right.
Tried to respond to your emails Cameron, they all bounced. =(
That particular tower would have added the essential features to a
regular VIC chip that allowed emulation of the C128 mode, but probably
not clock doubling. The programmers would have been able to write to
the most important add-on registers, etc.
The date is real interesting to me, it shows that there were no custom
IC's with a little over two months to go to CES, VIC was the easiest and
first chip completed (Dave DiOrio) and obviously didn't exist as we were
still modding the emulator halfway through September.

It's off the prototype 128. I'm still working on my own set.
