I therefore expect that there was 460-entry list of

predated 2-Jun-1979, and likely went back a few years. Two other
versions of sysdpy.mac in my archives have also dropped log messages
before 461.
The copyright notice goes back to 1976, which is about then TOPS-20 was
first released, right?
Is this a TOPS-10 version of SYSDPY? It was copyrighted in 1970.

Even before TOPS-20, on the CDC 6400 SCOPE operating
system, there was
a similar tool (whose name I no longer recall) that gave a
continuously updated display of system-wide process activity. That was
available in at least late 1973.
I didn't mean to start a mine-is-older-than-yours, but anyway, PEEK
is documented in AI memo 169 from November 1968.
