I haven't touched a Univac since 1979. So I forgot a few things. But still, the

FORTRAN-77 and someone else built the interface box.

PDP-6, decsystem-10 and decsystem-20 had 36 bits. Vax broke the mold.

It was NASA. They were using old equipment. I don't remember
which DEC boxes they had, I was told that the I/O interface was
16bits wide.
But, the Space Shuttle flew in spite of the fun we had writing
the ground support software. -- Goddard Space Flight, Beltsville MD
