Hitachi Micro Software Systems BeOS 5.0 Pro for x86 and PPC Used This OS was created by Be Inc., founded in 1990 by Jean-Louis Gassée, who was in charge of development at Apple. Instead of basing it on existing code like UNIX, they rewrote everything from scratch. It's a phantom OS. Used item. I don't have the knowledge to check its operation. It's a rare item(^^) If you are interested, please purchase it.
