It did, so long as there were parts for it.

It was running a high speed manufacturing line.  If memory serves, 
roughly 1200ppm, so 20 parts per second.

For a digital system that's a budget of ~50 milliseconds total 
processing time per part, which one can see how early digital stuff 
couldn't maintain that pace, but as PCs got faster, it wasn't really 
clear why it remained a "too hard".

That seemed to have come from the architecture.  Its a series of linked 
tooling station heads, with each head has 22? sets of tools running 
basically in parallel, but because everything was indexed, a part that 
went through Station 1 on Head A, then went through Station 1 too on 
Heads B, and Station 1 on C, 1 on D, 1 on E, etc ...

The process had interactive feedback loops all over the place between 
multiple heads (& other stuff), such that if head E started to report 
its hydraulic psi was running high, that was because of an insufficient 
anneal back between B & C, so turn up the voltage on the annealing 
station...and if that was already running high, then turn up the voltage 
on an earlier annealing station.

But that wasn't all:  it would make similar on-the-fly adjustments for 
each of the individual Stations too, so if Tool 18 on Head G was 
complaining, they could adjust settings on Tools 18 on Heads ABCDEF 
upstream of G .. and HIJK downstream too if that was a fix too.

It must have been an incredible project back in the 1960s to get it all 
so incredibly figured out and well balanced.

The modernization eventually came along because the base machines were 
expensive - probably "lost art" IMO - but were known to be capable of 
running much faster, and it was finally a modernization to have it run 
faster that got over the goal line for digitization.  I think they ended 
up just a shade over 2000ppm; I'll ask the next time I stop by.
