What's the oldest technology you've had to deal with in your career?
I happen to have an emulated CP/M 2.2 installation quick to hand to run old word processors, so let's take a look.
- Running CP/M on the Raspberry Pi Pico
- What is a good "lower level" language to learn after learning python to gain a deeper understanding of computers?

Ask HN: Are impressive new programs being written for CP/M?
There are no doubt some systems still running under emulation doing the same thing as they were 40 years ago. But the truth is CP/M is dead. Long live CP/M!
It's just hobbyists now. One hacker ported his game to a Kaypro under CP/M a couple years ago: http://www.chrisfenton.com/dd9-kaypro-edition/
Much of the focus is on porting CP/M to whatever new or old Z80 system someone has built or found. I can't think of anything particularly dazzling besides the above, in terms of recent new programs, but here are some pointers if you wanted to write something yourself!
RunCPM is a CP/M Z80 virtual machine under modern OSes for development etc. https://github.com/MockbaTheBorg/RunCPM
CP/Mish is an attempt to bring all the free software CP/M tools together. It is to CP/M as Linux is to UNIX, or FreeDOS is to MS-DOS. A mostly complete, improved, libre reimplementation: https://github.com/davidgiven/cpmish
Also from David Given (and not CP/M specific) is Cowgol. Alpha quality. But it's a self-hosted Pascal/Ada-like language with compiler. Runs on 8-bit systems, at least theoretically. It is written, of course, entirely in Cowgol: https://github.com/davidgiven/cowgol
Millfork is a language which targets CP/M systems, among others. It's a whole-program optimizing compiler for a language somewhat lower level than C, with properties that make it very nice to compile for 8-bit systems like no recursion, and no automatic promotion to 16-bit integers in type handling: https://github.com/KarolS/millfork
SDCC supports the platform with C surprisingly well. I wouldn't call it rock-solid but compared to the above toys it is an industrial quality compiler for the Z80. In fact, C seems to be the most common actual language for hobbyist and the little remaining serious Z80 development, probably ahead of assembly.
If it just reads and writes the terminal and can fit in 64 KB, then a port is probably straightforward.
