It is possible that something written for the LINC would be run in LINC mode for high

It could be that such code was modified from LINC code to a PDP-12 routine using the 12
as a "development system" to test and implement such patches.
I can verify that LAP-6 ran without touching a single word
of the tape on a PDP-12. We had a machine with two of the
fixed-head hard drives, and they emulated a (very fast)
LINCTAPE. You could copy your system tape to the hard drive
and then boot off that by setting a different instruction on
the front panel switches, and it ran like lightning.
