Thank you! You've found a goldmine of information! ^^
I'm currently reading that adverts category and the Oak video chipset faq..

Better yet, the manuals and specs and sometimes drivers are available on their US site...just go to the support section, click "Browse by product category", then "Other products" and select the appropriate option. Now this is a manufacturer that understands what "legacy support means". :cool:


Argh...two months later they've revamped their site and the contents on old hardware is gone... :depressed:

Oh, well, that's sad. :sad:

But at least the content is still on the servers! :)

Here's the manual for the "Epson Endeavor 486C", for example.
https://files.support.epson.com/pdf/en4c__/en4c__u1.pdf

A list of old Epson products can still be retrived from Archive.org.

I'm confident, with a little bit of googling,
it's still possible to save most of the manuals and datasheets.

Edit: Edited the title, since the thread has evolved. :)

Found a little page about PC98 (some kind of a buyer's guide):

Hello again! Just found another interesting page.
It's about Windows/386 for PC-9800 Machines.

Here's a page listing various operating systems for PC-98 and PC/AT:

And here's what I've found out about Windows95/98/98SE/NT until now: http://www.vogons.org/viewtopic.php?f=25&t=51090&start=20#p561964

What's also interesting is that the first version of Windows with proper USB support on PC-98 systems was Windows 2000.

Update. Dos-J Plus (DOSJP), the Japanese font utility for western DOSes, seems to work OK on 286 machines with EMU386 beeing loaded.
This is nice for DOS/V games, which do otherwise run just fine on pre-386 machines.

Quick update. Found a website which describes the different sound boards for the PC-98 series.

http://island.geocities.jp/cklouch/column/pc98bas/pc980186.htm

Translation : English / German

Long story short: Both PC-9801-26 and PC-9801-86 were popular standard boards.
The PC-9801-26 ('85) featured an OPN, while the PC-9801-86 ('93) had an OPNA synthesizer chip.

In contrast, the PC-9801-118 from 1995 had an OPL3, just like the western Sound Blasters/PAS16s of their time.
According to this source, it also had got an YMF 297 for backwards compatibility*.
It was probably made to provide better support for the upcoming Windows 95.

(*Speaking under correction)

Edit: According to this source, the YMF297 was a combo chip.
It included functionality of both YMF289(OPL3-LV) and YMF288(OPN3-L).

Little update. I did take some video recordings of a few DOS/V games, incl. openings w/ OPL2/YM3812 musical score.
- For comparison with their more popular PC98 releases found on the web..
