This would be the Interactive Systems V6 port, I think. At least that is
what wikipedia says:
"ISC's 1977 offering, IS/1, was a Version 6 Unix
<https://en.m.wikipedia.org/wiki/Version_6_Unix> variant enhanced for
office automation running on the PDP-11
<https://en.m.wikipedia.org/wiki/PDP-11>."
But there is a V7 after it, so maybe it's a Version 7 port instead...
