Cray-2 CPU
One of up to 4 background processors in a shared-memory Cray-2 system, cycle time 4.1 ns (about 244 MHz); the whole board stack ran immersed in Fluorinert.
Why this part
cray-history.net's detailed technical page gives 4.1 ns (244 MHz); a separate Wikipedia extraction gave an 8 ns (125 MHz) figure for the same machine. The two do not reconcile and this dataset uses the more detailed cray-history.net figure, flagging the discrepancy rather than silently picking one.

“Units recorded” sums only the edges where a public source states a quantity. It is a floor, not a total, and should never be read as installed base.
