They make an optional "speed box" that might make 78 possible, but
it's not totally clear from the site whether it's compatable with all
models (it isn't compatable with the most expensive model because it's
already electronically speed control). I'd write them just to make
sure, if you decide to go that route.

There's more involved to play 78-ers than just speed.
Needle dimensions, tracking force, antiskating.........
Not to mention the possibility of vertical vs. horizontal cutting.
Therefor, it's important to use a STEREO cartridge, as this type can
handle lateral movements.

That's a good point (pardon the pun). There are dedicated 78
cartridges with the proper profile. A good compromise is getting a
detachable headstock tonearm and having a spare headstock with such a
cartridge installed for quick changeout. Unfortunately, this isn't
possible with the ProJect turntables.

Or, one can just get an older 78 compliant turntable as a second unit.
You can probably pick one up for a song on eBay nowadays.

Then there's the variety of equalizing characteristics that were used.
The latter can be done via software, I suppose.
One could also build a dedicated preamp with a selector switch for
most equalizing time constants.
I once did this for a client of mine.
9 different eq curves, 6 tubes and a separate power supply.
AFAIK, the guy is still using it, to his utmost pleasure.
