I'd like to hear more about the 8032 memory expansion.
I am preparing a new version of the PETIndex and will add
an extension page where this would fit nicely.

However, I doubt this is the same chip as in the SuperPET - 
the SP 6702 only has power supply, data bus, some address and
chip select lines, Phi2, R/W and /RESET only.
No other connections. Also in the 3-board edition of the
SuperPET the 6702 had its own separate board to be plugged
in one of the other two boards. I don't think it is
a DRAM controller.
