I agree with could have been clearer. Had they used Helvetica, instead of a Helvetica derivative, it would have been more obvious this was a Swiss store.
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."

We should call them punch cards!
But 40 CHF (approximately the same in dollars or euro) is pretty good for a tiny computer with a screen and a pile of sensors and an easy programming environment.
