At least not from a practical perspective.
From an economic perspective, stopping after a single small run is just wasteful. The upfront design costs are so high, and the per wafer costs are so slow that you might as well make a lot extra. Maybe you can find a use for them, or sell them to someone else.
I read they had their own fab, so the minimum production run aspect would appear moot.
Back then an interface between terrestrial computer systems and a Zeta Reticulan spacecraft required a small supercomputer on our side.
