The installer shows not one but two splash screens: B-right/V TRON OS first, and Chokanji V second. Then it starts a very simply-looking disk partitioning and OS installing tool. Make no mistake, at this point TRON OS is already running. The mouse cursor is a bit funny/unusual, showing cup of green tea whenever there's a delay ("hourglass").
While it loads, you might contemplate: why did they bother to make a whole OS? Well, my dear friends, they needed a system that could support kanji, RTL and vertical input before Unicode was invented.
The installer partitions and formats the disk, asks whether you want full setup (all fonts) or minimal setup (less fonts), copies the files, and invites you to remove the floppy from the drive 0 and reboot.
