Back around 1970 or so, I did a performance study on a S/360-30. At
that time, IBM published instruction times somewhere--don't remember
where. But I came up with a result that said that a mod 30 was an "18
kip" machine.

Well, that presses all my nostalgia buttons at once! The 360/22 was the
first computer I programmed or operated. We ran HASP RJE on it, and
then (once we got to a full 64K of core memory) ran DOS/360 release 26.2
- though at one point I did an OS/360 PCP install. You could watch it go
CPU-busy parsing a DD statement.... Not the fastest machine!
I think the only technical differences between the 30 and the 22 was
that the 22 was lobotomized enough to reduce the maximum RAM you could
put on it, and had slowed-down channels so you could attach 2311s but
not 2314s.

The 360-22 was a very late model of the 360 series, introduced after
the 370s were available (perhaps 1972?). The -22 was actually a
relabelled -30, to use of those which came back to IBM off
lease. Rightpondians, think of a Ford Popular. It was thus a full
member of the 360 series. -22s were popular to use as HASP
multi-leaving RJE workstations, because they could drive real 360 I/O
devices, most notably the 1403-N1.
