DOS/V ? Tera Drive HDD image ?


Gutsy Member

1.) I once made a wild mix of "Hiragana, Katakana, Romaji and Kanj" using the DOS tool vgafed30.
Just to get a glimpse of "how it could have looked"....as I cant find DOS/V and or japanese BIOS ROMS anywhere.

2.) Im also wondering if a "Sega Teradrive HDD dump" is existing anywhere and if the menus of the "TeraDrive" are stored as files or within the BIOS.

The TeraDrive is one thing I'd like to get before I leave Japan next year, so I might be able to help out at some point.

DOS/V.... Man haven't heared that for a long time... <img alt=":)" class="mceSmilieSprite mceSmilie1" src="styles/default/xenforo/clear.png" title="Smile :)"/>

Wish I could help but unfortunately the hard drives I used in my Model 3 shipped with no hard drive... Had to scavenge some cables from an IBM PS/2 80286, not the 8086! The hard drives I ended up with were zeroed out pulled from working non-TeraDrives.

Nemesis is definitely the man with the full hard drive image, but he only appears sporadically... Or maybe it is me who appears sporadically?

As a side note, I use the XTIDE BIOS with some disk on modules to keep them living. But if anyone ever does need a TeraDrive compatible hard drive, feel free to message me. I've got three of the things and only one of those is installed <img alt=":)" class="mceSmilieSprite mceSmilie1" src="styles/default/xenforo/clear.png" title="Smile :)"/>

Meant to circulate this years ago. This image has the famed "Puzzle Construction" software on it. To my knowledge, this is the only copy that has ever surfaced of this software. This unit originated from within Sega itself. It appears it was a demo unit or reference unit kept within a sales department of Sega, which makes sense given the low serial number (201). I managed to salvage email fragments from this drive image, some of which I put up here:

There's also pieces of inventory data scattered across the drive image. Makes for some interesting digging. I paid over $2000 for this unit back in the day (including keyboard/monitor), which was a small fortune, but the data finds made it worth it.

Oh, and the software. Here's some floppy disk images I've made/acquired:

I've never properly dumped the BIOS files from the TeraDrive, but that would be worthwhile doing. I had plans to make a website with info about my collection, but I've never got around to it.

I had a bit more of a dig at that drive, and retrieved some more internal data from Sega. Here's a presentation which was apparently prepared for the CEO of Sega on the TeraDrive. It may have been incompete at the time, because it really only seems to show manufacturing numbers for the Mega Drive. The file was prepared as a "Harvarrd Graphics" show (powerpoint in the days before powerpoint), but I've converted it to something that can actually be opened nowadays. There are also a few extra/unused slides that were in the same folder:

And here's the source manufacturing data on the Mega Drive that was used to make the above presentations. This was in a Lotus 1-2-3 spreadsheet, but I've converted it to an Excel spreadsheet:
<a class="externalLink" href="http://nemesis.hacking-cult.org/MegaDrive/TeraDrive/HDD/Salvaged/MASTER.xlsx" rel="nofollow" target="_blank">http://nemesis.hacking-cult.org/MegaDrive/TeraDrive/HDD/Salvaged/MASTER.xlsx</a>

And here's some of the complete recovered emails I had in text form before. These were WordPerfect docs that I've converted again"
<a class="externalLink" href="http://nemesis.hacking-cult.org/MegaDrive/TeraDrive/HDD/Salvaged/19JUL91.FAX.docx" rel="nofollow" target="_blank">http://nemesis.hacking-cult.org/MegaDrive/TeraDrive/HDD/Salvaged/19JUL91.FAX.docx</a>

There's also that inventory of Teradrive hardware I talked about. It appears to be in a database format with a "DAF" extension, which may or may not be related to the "Digital Anchor" database tools I can find only vague information about. The files seem to contain equipment/stock listings, including serial numbers for TeraDrive hardware, and references to other equipment. It's hard to get useful info out of it without opening it in the proper program to read it, but it would be interesting if they could be recovered and opened.

I can't get access again to it this very moment. I'm actually about to walk out of my hotel in Denver and begin a 30 hour journey back to Sydney. All the data is in that HDD image I posted above though. I used R-Studio to scan the drive for data, and pulled those files out of deleted directories. Some of the data is partially or entirely overwritten. There are a number of deleted database files on the drive, and a few of them may be entirely entact, but most of them are going to be at least partially corrupted, if not entirely overwritten. There's probably large chunks of recoverable data though. I'd suggest getting R-Studio and doing your own scan of the drive image, and you'll be able to find the files yourself, as well as anything else that looks interesting.


Gutsy Member

Its all spread fragments and a mess, but it is fun to explore the "deleted" stuff and very interesting :
contains the mentioned serial numbers and all kind of TeraDrive Models enlisted.
Probably fragents of a IBM Multiplan format, like some of the others, if not the japanese Lotus 1-2-3.
WordPerfect is enlisted right after the huge data table of TeraDrive Models.[/b]

The word SONY shows up a lot [b]...[/b] Toshiba...
contains all text from the game SIM CITY and enlists the TERRAIN EDITOR as well.
There are many references to the assembler and C files enlisted, probably <span style="color: #ff0000"> <b>the whole source code of SimCity.[/b][/span]
Which got released in 2008 anyway, but this 90s version could be truly different.

Its a <i>"DOS-V Version By Kiyotaka Kono"</i>

references to :
C:\123\DAYLY\INPUT'S.WJ2 <span style="color: #ff0000">(jap. Lotus 123)[/span]
C:\HG3\DATA\ROCKTOP.PCC <span style="color: #ff0000">(HGcopy Utility)[/span]


The music files dont look like the MegaDrive CYM format. The file header starts right with the instruments. Anyone got an idea ?

<img alt="music file header.jpg" class="bbCodeImage LbImage" src="https://assemblergames.com/attachments/music-file-header-jpg.15551/"/>

There are many many patterns that look and feel like parts of graphics, layouts and / or music...but as mentioned, it is a mess. <img alt=":)" class="mceSmilieSprite mceSmilie1" src="styles/default/xenforo/clear.png" title="Smile :)"/>

<img alt="SILKA lily of the valley.jpg" class="bbCodeImage LbImage" src="https://assemblergames.com/attachments/silka-lily-of-the-valley-jpg.15553/"/>

Now I know the CD ROM (Mega CD) never was released for the Teradrive and only 2 prototypes existed according to <a class="externalLink" href="http://segaretro.org/Teradrive" rel="nofollow" target="_blank">http://segaretro.org/Teradrive</a> .

So what about this tool/loader, why it already mentions MEGA-CD and who would SILKA (Lily of The Valley) be ?

The exe file says :

So does anyone still want a TeraDrive BIOS dump? I've got a Willems ROM reader/writer, and a Sega TeraDrive that's currently not working (PSU blew up from what I can tell but I haven't had the chance to open it yet).

So which chip is the BIOS?

<img alt="[​IMG]" class="bbCodeImage LbImage" data-url="https://i.imgur.com/28vXD1a.jpg" src="https://i.imgur.com/28vXD1a.jpg"/>

And the hard drive controller card seems to have an IDE port on it, but the cable that converts it to the proprietary IBM edge connector is the only thing that plugs into the hard drive leading me to believe that one of the IDE pins must carry power; would it be possible to mod the card to accept a regular IDE hard drive?
