Yotsugawa's Space

About me // カトリックの作品集 // Macintosh // Literature

Welcome to the Yotsugawa Classic Macintosh page.


Power Macintosh G4

The purpose of this page is to document my activities in vintage computing, primarily with Mac OS 9.
Unfortunately this site does not load on Mac OS 9 browers because it uses https encryption. This site is being constructed using a modern computer but its home is on the Classic OS, and I would like to see it viewable on Classic in the future.

List of vintage machines I currently own: (14 May 2021)

  • iMac DV 450 MHz Indigo (July 2000) // Mac OS 9.2.2
  • Power Mac G4 933 MHz ("Quicksilver 2002") // Mac OS 9.2.2 & 10.1

I am also in possession of a Hewlett-Packard Pavilion 8201 (manufactured 21 Nov. 1997) running Windows 95.


  • 18 Mar. '21: The Quicksilver, which I purchased last year off Facebook Marketplace, which was running Tiger, has been system restored and is now running 9.2 (main boot) and 10.1. I have ordered an SSD and a quiet Nocturn PSU fan to help quiet down the machine.
