A guy named Roger Roach who is or was at MIT
supposedly has magtapes containing the CTSS
documentation. If he does still have them,
I doubt he would release them from his possession,
and I don't think he personally has the time
to try to recover the contents.

He might permit a researcher access to the
tapes at a facility local to MIT or wherever
he now happens to be.

I do not know Roger; I got this information
from a third party.

Most of Multics is written in PL/I; unfortunately,
PL/I compilers are hard to come by.

I, too, have had Java recommended to me as a language
for implementing emulators. I have concerns about its
performance.
