"P11" was the extension used for PDP-11 assembly files very early on. I assume
that was because they were cross-assembled on a PDP-10. Presumably PALX11.MAC
which is on one of the other tapes!
One of the tapes seems to be a SNOBOL implementation, with LOW and HGH and SHR
extensions which sounds vaguely familiar from long ago when I briefly used
TOPS-10.
Another has SIMX11.SAV, wonder if that might be MIMIC. That would be quite a
find. And on the same tape IOX.P11, that sounds like the early "papertape I/O
executive".
One tape is labeled "New PS/8".
BASIC.P11 could be the RSTS BASIC code, that too would be a very interesting
discovery with that date. SYSLOD is the DOS installer. RDT I don't recognize.
I'm seriously looking forward to seeing image files of those tapes.
