Not shure how usefull it is.

EDIT:
What does the label on the drive say?

Could be a Mitsumi or Panasonic interface. Both used 40 pin connectors but weren't compatible with IDE. Sony's interface used a 34 pin connector.

Whats written on the back above the controller connector: `BUS` or Interface.

If its BUS then its one of the early proprietary ones. If its `Interface` It could be one of the earlier IDE drives.

I see that the drive uses the old style of molex and also year 1994 saying that it could be an older proprietary drive.

Those older drives dont work on an normal IDE interface.. So it wouldnt death after all..

Maybe this could help:

As Pictured, a NEC 2x CD-ROM, CDR-260.
This drive uses a special driver (included on floppy), not standard ATAPI.
Pulled from a working machine.

Returnable if DOA (shipping is non-refundable).

Details from http://support.microsoft.com/kb/131499:

NEC CDR-38, NEC CDR-250, CDR-260, CDR-260R, CDR-260GW

The NEC CDR-38, NEC CDR-250, CDR-260, CDR-260R, and CDR-260GW CD-ROM drives are incompatible with the ATAPI specification version 1.2. Therefore, Windows cannot detect these drives if NEC_IDE.SYS is not loaded in the Config.sys file and MSCDEX (or equivalent) is not loaded in the Autoexec.bat file. After Windows detects these drivers, it uses protected-mode drivers to access the CD-ROM drive.

For information about the parameters for NEC_IDE.SYS and MSCDEX, please refer to the drive's documentation or contact the manufacturer.

Results for the driver:

The above basically says its IDE (electronically compatible), but the drive doesn't use a standard command set, thus needs a special driver.

I think I have one of those... it's filling an empty slot in an old tower. The front looks about the same.

I'll show you once I get my 3.5 card reader attached to my PC. I took a picture but i'm Kinda busy at the moment but thanks for the replies so far. 😉

Had to use my Kodak camera cause my Flipvideo camera I used for the first pics does not have good focus.

If you look at the back pic, the drive does not have CS/SL/MA jumpers. It has 6 unnamed jumpers in place.

Cool one. I like weird optical drives. 😀

Apparently NEC's ATAPI spec predated the standard by a little bit. The same model was updated to conform not much later, '94-'95.

It was made by NEC ? Cool! Maybe it was intended for the PC98 then. 😀

According to this site, a similar model was used in the PC9821-Ce2; The NEC CDR-260(PI).
If this one is indeed related to the other NEC model, it would be legitimate for this unit to not to comply with ATAPI.

..And it would be then have been a nice move from NEC to supply a driver for the competiting platform.

Edit: Sorry for the bad wording. My English is broken for today.

Here we go folks: pics of the drive:

(optimized for 1024x768)

Interesting, the label also shows an 8/16bit jumper setting.

IDE ATAPI CD-ROM. In case not recognized by drivers: trash time. 😀

Yeah trash it to my home, then i try to getting it working.

Iam sure it needs the NEC special IDE drivers, Cause in 1994 atapi seems not to exist.

The 8-bit / 16-bit settings is only when you using an non music card, but a seperate CD ROM I/O controller interface board..

When this interface board is 8-bit you need to set this drive to 8-bit operating mode.. If this controller is a 16-bit one, it needs to set to 16-bit on the drive as well.. Its straightforward.

I insist on trying to get it to work before I trash it... It can't be ordinary IDE ATAPI due to it having SIX rear jumpers. BTW they used to ship proprietary drives with creative sound cards back in the day. Like I said I believe it came out of an old Gateway P5-100 case when I received that with a bunch of other computers and parts years ago.

I'll fool around with the drivers once I bring a system from storage old enough to test in with.

I like non IDE drives, they can be useful on older PC's with just the 1 IDE channel. (Ok you can use a IDE drive with a sound card but that's not as cool)
They make good rainy day projects finding out what type of drive it is

I am almost sure it is for PC98 computers, they used somekind of CDR-260 drive in those.

EDIT: Found a picture gallery. http://retro-type.com/PC98/, the picture in http://retro-type.com/PC98/cdrom_external_back.jpg sure looks familiar doesn't it?

I have an NEC CDR-271 ATAPI CD-ROM almost identical to this one except it ix 4X speed, the CDR-260 is 2X. My CDR-271 also has a six jumper header.

I was digging around Google and found some info on this drive (mostly translated from Japanese.) It seems to be an early ATAPI and might require special drivers to work. Someone had one on his Gateway desktop, but couldn't get it to work on his new motherboard: http://discussions.virtualdr.com/showthread.p … ith-NEC-CDR-260

This is just an idea, but.. I think the NEC CDR-271 was released about a year after the CDR-260.
By that time, market share for the PC98 already dropped and DOS/V （ドスブイ） computers gained popularity.
Beeing aware of this, it would have made sense for NEC to slowly give up on its PC98 platform and prepare to move to PC98 NX,
which essentially became an IBM PC compatible platform. So it's no wonder this model was already made ATAPI compatible.
It wouldn't have made sense anymore to keep using proprietary interaces without an proprietary platform to use them for.
Other evidences for CDR-271's release date beeing somewhere in '95 are posts dating back to '95 and drivers from '96 (no CDR-260 support, btw.)
This was also about the time ATAPI was available in its final form. In early '94, it was still in draft stage.
