AFAIK only the first release of M3 used C as intermediate code.
Later SRC releases used gcc as backend. I don't know if any of
the old archives are still accessible somewhere.

SRC never used/provided a public version control system (though they
internally had bindings for Vesta AFAIK).
(For Vesta, see http://www.hpl.hp.com/techreports/Compaq-DEC/SRC-RR-168.pdf.)

So there will be no public record of the old compiler sources in any
repository.
