When you get there, you find the place deserted though.
Ultimately you must rescue the professor by finding 3 missing prisms which control his time machine, which are lost in time.
As the other games in the series, the game uses an interpreter similar to the Scott Adams adventure engine, and thus also has the same limitations - a basic 2-word parser, limited vocabulary, and brief descriptions.
Illustrations are included in ZX Spectrum, C64, Amiga, Amstrad CPC, Atari ST, Dragon and Oric ports.
About Commodore 64
Released in 1982, the Commodore 64 is the best-selling home computer model of all time, with an enormous software library spanning games, productivity tools, and everything in between. C64 game collecting centers on cassette tapes and floppy disks in their original packaging — physical media that's inherently fragile, so complete, working copies from the era are increasingly prized by retro computing collectors.
Gamevaro tracks Time Machine for Commodore 64 with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Time Machine to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This C64 release dates back to 1990.

Rarity & condition
Only a handful of market sales have been tracked for Time Machine, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Commodore 64 titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
