#PC98

Made a new video: Setting up an NEC PC-9821 Ce2 with a fresh hard disk and DOS 5.0A-H (using a very large IDE hard drive). Also CD-ROM drive setup.

As usual correct me if I'm utterly wrong about something.

高校入って初めて手にしたPC
詳細は覚えてないけどWin3.1がインストールされてて、後から95にしてもらった記憶力

親の知り合いから譲ってもらったんだけど、こんなに高いものだったのか…
いくらで譲ってもらったんだろうか😱

Sometimes I wonder if the game composers who worked on PC-98 porn games went so hard because the games were porn and therefore "didn't matter", so they decided to go all out instead of phone it in OR if they saw porn games as a genuine genre of game and so they put their all into it.

It makes me think about the differences in porn games now because like I can't think of a single modern porn game that I can praise for its artistic/musical qualities. Maybe I'm just not looking? I dunno.

Vydán nový překlad

16bit Sensation | 3. díl

Manga zasazená do devadesátých let se věnuje rozvoji eroge průmyslu očima mladé kreslířky Meiko, která však zatím s lechtivými ilustracemi nemá žádné zkušenosti. Dílo, ač fikční, je i díky mnohým konzultacím z řad dalších eroge tvůrců velice věrohodnou výpovědí o specifické části eroge subkultury devadesátých let.

(Převzato z novinkového serveru konata.cz)

@mctek @evv42 @nina_kali_nina Any of you got any idea how i can make this PC-98 mouse not sound like metal grinding on metal (or like scratching a chalkboard) as it moves?

Goodie number 3: yet another bus mouse I didn't need but it was cheap so I got it anyway.
Sadly, it does not contain the bus mouse ISA card. But my olivetti M24 has a bus mouse port built into its keyboard (with a different pinout, so I'll need to use an adapter).
I have a hunch this will work without changes on my PC-98, I bought this mainly to test that theory for my blog post since the logitech C7 is relatively affordable as long as you don't get the translucent version.

Logitech C7, a very boxy and rectangular mouse from the 80's, with the box that has magenta and teal accents.
