The 1620 that I had access to had PDQ ("pretty Damn Quick"?) FORTRAN,
and a 1401 emulator!
Being students, not administrators, we had VERY limited access to the
1401, but unlimited access to the 1620, and learned 1401 machine language
on the 1620. VERY limited memory, but you could use the input and output
buffers as RAM when you weren't reading nor writing.
