In any case, it would appear that the vinyl 78's were designed to be
played
back with a "normal" cartridge sporting a 78 stylus; there are cartridges
that will accept both LP & 78 styli, albeit at a higher tracking force
for 78.

In most ordinary record players, cartridges used to be "turnover" for many
years after the introduction of fine groove records. The cantilever had
two styli and you turned a small knob on the front to change between fine
and coarse groove. I don't remember anyone changing the playing weight
though, it was probably about 5 g for everything.

That's right, and in most cases, the microgroove stylus was diamond and the
coarse groove stylus was sapphire. As this one would wear very quickly, so
anyone who still regularly played 78s, would probably be playing them on a
worn stylus and so cause a lot of damage to the record. One further reason
why there are so few unworn 78s available now.
