"NASA uses five general-purpose computers in the Shuttle. Each one is
an IBM AP-101 central processing unit (CPU) coupled with a
custom-built input/output processor (IOP). The AP-101 has the same
type of registers and architecture used in the IBM System 360 and
throughout the 4Pi series. IBM announced the 4Pi in 1966, so by the
early 1970s, when Shuttle procurement was complete, the machine had
had extensive operational use. The AP-101 version, which is an
upgraded AP-1, has since been used in the B-52 and B-1B military
aircraft and the F-8 digital fly-by-wire experimental aircraft. The
central processor in each case is the same, but the IOP is adapted to
the particular application."

"Each CPU is 7.62 inches high, 10.2 inches wide and 19.55 inches long;
it weighs 57 pounds. The IOPs are the same size and weight as the
CPUs."

"Due to packaging considerations, the core memory is located partly in
the central processor and partly in the IOP (they are boxed
separately). However, it is still considered as a single unit for
addressing and access."

Czyli w sumie 114 funtów na komputer z pamięcią i układami IO. I pięć
takich komputerów na szatla... Trochę to ważyło.

Przy czym wybór IBM AP-101 jako komputerów dla szatla dokonał się w
