Is the extron necessary for the DT-V? I have one and have been using X68000 straight through vga to bnc. It treats the image as a widescreen resolution though, and I have had to make a lot of adjustments to get more screen real estate because of it.

! Great work !
thanks a lot

Absolutely! Have at it.

This is awesome! Would you mind if I include it in my HDD image with a write to disk batch file?

Thanks for the info. I haven't tried working at it in a bit, but I did find some leads I'd like to try and was planning to share the steps here if it worked out. I'll give yours a go since it's pretty simple next time I take a stab at it. Thanks for the write-up!

Hi,

I don't know if you've found a solution since your post, but since I had similar needs, I'll share my experience:

mTCP's developer reported recently that mTCP does not work on PC-98 machines. I've lost the related post, but I think it was on Vogons.

I tried the TEENE route. TEENE implements a full TCP/IP stack for Ethernet cards on DOS PC-98 machines, and uses packets drivers to talk with the hardware.

The self-extracting archive you've found on Buffalo's website contains a packet driver, namely \pktdrv\lgypkt.com.

The simplest TEENE setup would be the following (if it works, you can put it in your AUTOEXEC.BAT):

REM start the packet driver, here configured with default settings
A:¥TEENE¥LGYPKT 0x60 3 0x00D0
REM set up the TEENE configuration environment variable to point to your TEEN.DEF file
set TEEN=A:¥TEENE¥TEEN.DEF
REM start up TEENE
A:¥TEENE¥TEENE.COM

At that point, if your TCP/IP configuration in TEEN.DEF is correct, you'll be able to ping your PC-9821 from another computer. I'm not sure TEENE supports DHCP, you might need to setup up a static IP address.

TEENE does not come with any "client" for anything; I found a compatible FTP client on http://www.abk.nu/~kattyo/freesoft.htm#prog_ftp, look for KFTP006.LZH.

About LSL.COM and IPXODI.COM, you'll only need them if you intend to use a Novell Netware client... or if you cannot find a packet driver for your Ethernet card (it was my case).

The .DOS file you configured in config.sys is the driver for Microsoft LAN Manager, yet another MS-DOS TCP/IP stack (among other protocols); if you use TEENE, you won't need it.

For reference, my TEENE configuration (TEEN.DEF) is the following:

;TEEN v0.36 定義ファイル(Ethernet 版用)

both buttons & leds connector from X68k are 2.00mm pitch.
I bought all components that i hadn't in my folders from aliexpress and ebay, so no BOM to share, but they're all easy to find. Be aware only to 74lvc245, i got some fake ones in the past

Great project!
I order my PCB via FusionPCB by uploading your GERBER-X68KFDPI2.zip.

anywhere Parts List ?
1 x 74LVC245
1 x MicroSD Connector
1 x Buzzer
1 x 1N5817
6 x R330
3 x R4k7
2 x R10k
2 x LED:Green
2 x Tactile SW

LedFD0 / LedFD1 Headers with pitch 2.0mm
and other Headers with pitch 2.54mm OK?

So I was talking with some folks the other night and it was brought to my attention that I never did a broad release for this.

Basically I got tired of what a mess the original Master Disk is (no shade to eidis, I'm glad it exists) and I redid the whole thing from scratch using DSHELL (the interface for Dennou Club diskmag) and included as much useful stuff as I could fit on the disk.

Besides a bunch of helpful diagnostic stuff and a couple of bootloaders (SxSI and BM) for immediate use I put some stuff in LZH archives that are also useful but need to be decompressed and stuck on an HDD or something. This is an exercise for the user.

I also included some explanations of common file formats and how to use some the tools included in the archive. There is a description of the important options in SWITCH.X and what their defaults are and their behavior.

Please be patient when it boots, it takes a little while. It decompresses the usable tools from an LZH into a RAM disk. This saves space on the disk and ensures that everything works even on machines with only 1MB of RAM. Also understand that this disk is full (48K free). There is no room for anything else. If anyone thinks that it's missing something really important please let me know and I'll consider making a second disk to go with it.

I hope you all like it and find it useful. My only request is that if you sell it please only charge for the disk and shipping. I did this because I love this community and it's important to me that we share freely!
