Oxocards: Interactive programmable minicomputers • Hacker News Board

Their website has not prevented me from finding out what this is! It is hardware. I even found some photos elsewhere: https://www.digitec.ch/en/page/oxocard-learning-to-programme...

Horrible misuse of the term Minicomputer. So triggering!

I'm guessing a language issue, though. Since it's a .ch site maybe their first language isn't English

I was so excited to see a minicomputer on a card. And then... this. So disappointing.

This may be of interest [0][1][2] to the minicomputers should be mini people.

Looks like they ported SIMH to an ESP32 to emulate a PDP-11, to run the original tetris for the Soviet PDP-11 clone (Elektronica60), and 3d printed a mini VT-102 case to put it in.

And also 2.1 BSD..

FTA: "ESP32 was configured to emulate an PDP11-23 with 256K of RAM and a RX01 floppy disk drive, giving me 256KB of disk space for the operating system and game files. I used SIMH on my laptop to create a blank disk and installed RT11 onto it. Next, I took the Russian games disk containing Tetris and copied the binary over. That disk image would get flashed alongside the emulator to the ESP32. I didn't bother with the terminal as of yet, instead opting to just pipe the console of the PDP11 out of the debug serial port of the ESP32."
