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.

The Arduino board is only used as a PSU & USB serial, no cheating here.

I've... exploited 0days you programmers wouldn't believe.
[*contemptuous laugh*]
ROP shellcode on non-executable memory ran as the machine of Turing.
I watched Offset2lib pwns ASLR near the stack of kernel space.

All those bugs won't be fixed in time, like
[*cough*] dereference... to... NULL,
segfault (core dumped)

I want to like vscode but I just can't get past the idea of using a separate application window for editing files and navigating the filesystem. It might take longer to type what I want in a terminal than it does to click through a file tree but the idea of moving my hands off the keyboard makes me cringe

Except I had some 2nd ed, probably:

The Lost Treasure "simulation" was a big influence on the games I still write 4 decades later.

I've been wanting to redo XRAY, but the original pdp8 platform seems like a real pain. 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.
