This CPU card was covered on one side in surface
mounted 100000 series
ECL, which I believe is the same as F100K.
Yes it is the same. There was (is?) a newer, faster family called 100E,
the ECLipS family by Motorola. I think it died out with F100K.
The other side of the card
had a thin layer of insulator and a thick layer of steel - presumably to
interface thermally to a cooling system.
That sound similar to the system incorporated into many earlier Cray
machines, except that the Crays used a copper sheet.
