Has anyone other than the owner of m88k.com preserved Motorola System V/68? Besides that, there’s the SVR1 (v2.8) for the Motorola VME/10 on Bitsavers and that’s about it.
I’m especially curious as to whether anyone has preserved the SVR2 1.1 binary+sources distribution, since there might be useful information in it—or derivable from it—about much of the early VME hardware.
