I'm also on Altair!

The multi-system simulator SIMH is an absolute work of genius. One of the Raspberry Pis in our rack has been set up as an Altair running CP/M 2.2, with a number of programs like ELIZA and all sorts of other things, on the A and B drives.

You can connect to the system with telnet at altair.bencollier.dev:2380
