A few months ago, thanks to help from several people here, I converted

It seems that one of the PALs is maybe setting up the address!
Anybody else tried this?
I never tried it with a Dilog SQ703 and SQ706. The two that I have
have numerous differences between the boards, which made me skeptical
that just a simple EPROM swap would be the only change necessary.
However with the newer S-handle versions of the Dilog TMSCP SQ3703A
and MSCP SQ3706A boards that I have, they appear identical except for
the EPROMs. On those I did try swapping the EPROMs between the two
boards and that did appear to completely swap them between TMSCP and
MSCP functionality.
