8-Bit Show And Tell | The Tiny Type-In Hiding In A 40-Year-Old Blank Computer Cassette @8_Bit | Uploaded January 2023 | Updated October 2024, 23 minutes ago.
Is there a tiny type-in program listing hiding inside a Thorn EMI EMITAPE Computer Cassette? I tracked a brand new, unopened C20 tape down, thanks to a tip from viewer EdwardianTeaChest, and opened the early 1982-vintage cassette. There are in fact two listings, one for the Commodore VIC-20, and another for the Sinclair ZX81. Join me as we type these programs in on vintage hardware, and figure out what they do.
