BACK TO THE PET - a demo for Commodore PET

This is a demo for Commodore PET 4032 I’ve released at the CAFe 2022 demoparty. It is the party version’s video captured from a modified MAME build, exactly as shown on the party - I don’t have access to the real machine, and it got sound emulation issues in the current emulators.
