Unix V7

Session captured from a Nexys-2 board configured with an 11/45, RH11 + RP06, console, and extra KL11. The RP06 image was created from the original V7 distribution tape using SIMH.

In this session, we see how the extra KL11 serial controller is configured into the kernel; after that, the kernel is recompiled, some settings are changed, and the system is rebooted with the new kernel.
