It's been about fifteen years since I visited, but they had a big section on the evolution of the techniques. It started from hand lace making, then progressed through periods of different looms. From memory, I'm pretty sure they had a punch-card loom about 200 years old, that was actually operating while I was there.
Jaccard looms are too general, too unconstrained. I like shaft looms more gratifying. Their restrictions make it more interesting.
