As a travel company, we ran a reservations system by day ( CICS c 100 x 3270 terminals ).?
Overnight batch accounting, reports, backups overnight and development and testing streams.
CICS programs were COBOL, the biggest program was 8k compiled!?
operators fed in JCL, mounted and de mounted disks and tapes, and decollated tons of reports from the 1403 printer (extremely noisy).
as a systems programmer I spent all weekend doing updates and sysgens with the whole machine to myself. Bliss.
