This is a single .PRG file inside a ZIP archive which can be loaded up in nearly any VIC-20 emulator. Or, if you have the capability, like having a ZOOMFloppy or something, you can run it on a real VIC-20.
This program file was originally loaded from a cassette tape, saved to floppy, and transferred to a PC.
It’s not a fantastic demo by today’s standard, but it did show off what was considered rather catching at the time… color graphics and sound from a “small” computer.
