System 0.85

System 0.85, Finder 1.0 (Macintosh Guided Tour) System 0.85, produced in 1983, was provided on the original Macintosh Guided Tour disk for demonstration Apple Macintosh 128K computers. It was released with the "Finder" labeled as 1.0 (but older than the Finder 1.0 on the 0.97 boot disk); it booted directly into the Guided Tour software. This system only runs on the original Macintosh computer with 128k RAM, and pre-dates the retail version of the Macintosh System released with the Macintosh 128k.

The original Tour disk included the welcome screen, usage information, the Finder, the Amazing game, and Mousing Around. System 0.85 was incompatible with the final version of Finder 1.0 as found on the retail disks for the Macintosh 128k computer.
