that ran 1401 emulation as part of the general ledger processing,
The USAF spent much of the 1970s running their logistics system on
S/360 systems running in 7080 emulation mode. Heck, they still had
7080s until about 1974. Most of the code was written in 7080 COBOL
with patched binary decks and 7080 autocoder. A really horrible mess
with little documentation.
I've even heard of nested emulations: 701 emulation by a 1401 running
on an S/360.
I suspect sine state DMVs and other offices were just as bad.
