The 6180 booting up...
@snowdusk_ The 6180 is not UNIX, it is Multics, a predecessor of UNIX.
After fixing the "memory write" timing violation, my breadboard #Z80 completed the π calculation program flawlessly, and was able to calculate π to 500+ digits.
In the troubleshooting process, boards were rewired based on a "bus-centric" approach - always use a row of rightmost boards as the system bus, so new modules can be daisy-chained, and the bus can be probed easily.

It occured to me that an Atari 800 could stand in, and I (at least at one time) could make FORTH jump through hoops. Find an Atari Emulator. Check. Find a FORTH disk. Found a zip of 12 images; check. Download, unzip, look at the disk titles..... <cue eerie music> ... One of the disks is... an editor I wrote back in '83. #retrocomputing

Reading this makes me glad I use #OpenBSD and don't have to put up with "convenient" stuff like NetworkManager and systemd. :)
Deep into reading the Multics "AN61A Storage System Programming Logic Manual", I come across the lovely phrase
