By that logic, the only machines that count are the System/360 Model
85 and the 195.
Since the other S/360s and S/370s were air-cooled.
No. Every series until the IBM CMOS machines was water cooled as far as I
remember although not every model in every line was water cooled. Up through
S/390 and including the ES/9000. Even the lowly 43XX (which was more
powerful than the biggest VAX ever made) was watercooled.
Everywhere I ever worked until the CMOS days had watercooled machines and
raised floor. That was the real "big iron" worthy of being called machines.
