What do we have here? NEC PC-9821 laptop (non-PC compatible from Japan that can run Windows and a special MS-DOS version), running a rare variety of Linux called Plamo Linux/98. Linux 2.4.22, XFree86 4.3, and some Slackware compatibility. More screenshots - but from the screencapture device - will follow 🧵
Plamo Linux comes with an unusual window manager that is definitely not copied from Windows 9x, and doesn't have any icons from Windows 3.x. Geroware Qvwm is all animated, and thus fairly slow on a non-accelerated video.
You need to watch the video to appreciate how restless this window manager is! I don't think it's common for Japanese computing, by the way, just feels very hacker-y. "Hey I made these icons animated for fun! Also there's Oneko!"

"Netscape" button opens Wazilla - Japanese flavour of Mozilla. It can sort of open my home page, and Google.co.jp still works in it. Of course it can show Japanese characters!

The staff with kana "Mo" on the logo hints that 和ジラ might be a multi-level pun. Gecko/20030829 hints at the build date.

Of course, no modern cryptography.

Standard apps are not too strange. Emacs has a doctor that can make you feel better!
There are some games on the CD; Contrib CD has NScripter port so you could play Higurashi on Linux.
I want to install GNOME, which is done with a lovely script called 00INSTALL.sh. It reported that I miss a few packages.
@nina_kali_nina Since this is Slackware-based, you should also be able to use pkgtool to install sets from a menu.
@bytex64 I tried to run pkgtool from the "GNOME" directory and it just tried to install all the packages from it, asking "Yes/No" after each package. Maybe Contrib CD isn't fully supported or needs a separate command flag.
@nina_kali_nina Ah right. Maybe that’s all it did. It’s been a minute since I’ve used it. :/
