Often these parts can be replaced with MSI TTL counter/decoder/logic chips
with just a slight change in wiring.
I don't know if the SD102 is the Nixie driver, but there are substitutes
for Nixie drivers too.
I don't know exactly what the SD102 does, but if your friend has the
Monsanto 110B schematics he can see what the chip does and how to
substitute for it.
