Come on, we all know how this will end... a raspberry-pi like processor
running a virtual machine emulating the original processor (running the
same firmware) and taking care of everything digital, and the analog
asics doing what they do best.... HP48 style.

I talked about this with a friend who works for the semiconductor
industry. He had a feeling that the new 3458A meters don't last as
long as the old ones.
He had compared two faulty Malaysia made meters with close serial
numbers and found a component which had a 1980s date code in one meter
and 1990s in another.
He was a little worried about the combination of manufacturing in
Malaysia and buying obsolete components probably from the local
sources. When fake and "cleaned" components have found their way to
trains, aeroplanes and even defence electronics, why would the 3458A
be an exception.

Many components of the 3458A are already obsolete, or endangered by PTNs,
not to speak about all these through-hole components. I've already seen
pictures about a piggy-back solutions for several ICs, and maybe they have
to use that already for the new production, especially the two fast
comparators EL2010, U142 & U181, used with the A/D.
The 68HC000 is also obsolete in the DIL package, and the SMD package is 'not
for new design' already.
