Story of Mr. Robert, the bad ass #Unix porter, gets no less amusing afterwards.
There's a working self-hosting C compiler, various utilities also get ported to the Interdata operating system. But also -- parts of the kernel. The computer is in use during the day, so rebooting to test out a kernel is not an option! Towards the end of the development, Robert needs to test kernels at night.
They eventually switch to UNIX and call the Bell Labs about their port, and their collective jaws dropped -- they were also doing a port for an Interdata machine. But needless to say, had an actual UNIX computer!
Oh, and Robert didn't use that third round-trip! ๐ง ๐ช
