The Four-in-One Infocom Sampler

This collection bundles 4 Infocom games:

Infidel

Planetfall

Witness

Zork I

Just a small section of each game is included, the idea being you could 'try before you buy'. The sampler itself costs about $10, but you could either return it for a refund, or use it as credit towards your purchase of any of the games, so effectively it was free. The game was ported by Lee Burt aka Thanatos916 in 2022 for both 40 and 80 column display.
