       @SnoopJ@hachyderm.io @ricci@discuss.systems I don't see any obvious "unix.c" files or anything... but I do see that unix binary, which I'm assuming is the kernel.  What architecture and boot up chain would you even need to get that running, I wonder?... I realize I know nothing about boot up sequences from the 70s for UNIX.  Did they have something we'd recognize as a BIOS, I wonder...

       @aud @SnoopJ Well, at one point, you booted these things by toggling in the boot code using the switches on the front of the PDP, but I don't know the exact timeframe so I don't know if that would have been the way you booted in 1974

       @aud @SnoopJ @ricci The kernel source is in /usr/sys, the config in conf/mch.s can be switched between a PDP11/40 and 11/45, similar to 6th edition. Warren Toomey's apout seems to be able to run some of the included binaries, but I can't get the C compiler to produce an output file.
