In the fall of 1977, I experimented with a newfangled PC, a Radio Shack TRS-80. For data storage it used-I kid you not-a cassette tape player. Tape had a long history with computing; I had used the IBM 2420 9-track tape system on IBM 360/370 mainframes to load software and to back-up data. Magnetic tape was common for storage in pre-personal computing days, but it had two main annoyances: it held tiny amounts of data, and it was slower than a slug on a cold spring morning. There had to be something better, for those of us excited about technology. And there was: the floppy disk.
The source code of the classic Apple II game Prince of Persia has been published on GitHub by Jordan Mechner, the original author. The game, which was first published by Broderbund in 1989, was developed in 6502 assembly. With the help of Apple II enthusiast Tony Diaz, the code was recovered recently from a 22-year old floppy disk.
