I happen to own 2 specimen of the Philips NMS 0210 CD-ROM interface.

Today in the Philips Museum we tried to test them with the CDR-X1000, the Tele Atlas software I have and the Tele Atlas CD-ROM. And a SCSI cable. Unfortunately it didn't work. Nothing happened on the CD-ROM player. The only effect we could see is that the CD-ROM player would stop opening or closing if we reset the MSX whilst it was doing that, but only with the NMS 0210 that has the white label. With the other one nothing happened at all.

So, the question is... what went wrong? At least the owner of the CDR-X1000 is going to see if the unit needs recapping (it never spins up...)

Help we need:
- who owns another CDR-X1000, so we can try with another unit?
- who can help to reverse engineer the software?
- who can help to reverse engineer the interface cartridge, so it could possibly be recreated, making at least one component less rare... to this end I made an album on msx.pics with photos I took from my two interfaces: https://msx.pics/album/juXD The one with the label is the one with the light PCB and the black connector and the one without label is the one with the dark PCB and the blue connector. So, can someone devise a schematic from these photos? Can someone see whether something is wrong with these units?

The software has a demo mode (see https://www.youtube.com/watch?v=Nv9lIJXOu1U ) and if you press F1 or CTRL-STOP it seems to start the 'real' software. But that just shows "TELE ATLAS" and then hangs up.

I assume you checked SCSI termination and SCSI ID? Is it possible that the adapter firmware requires the CD-ROM to be set to a specific SCSI ID?

Ever thougt of an SASI interface just like the Ascii HD interface?

Rderooy: it is not SCSI and there is no firmware in the interface....

Hi Manuel,
Nice talking to you today! I would not mind lending a hand in trying to recreate the schematics and/or help reverse engineer the software.

Sorry, my bad. I just assumed it was SCSI.

Hello,

I am getting an original CDR-X1000 somewhere next week.
I would love to try this TeleAtlas software. Is there somewhere I can get an ISO or a copy of the disk?

If you get the 1 from Marktplaats you will first need an MSX interface cartridge as well. That model seems to come with a PC interface.

It looks like a SCSI or SASI interface for me.
Even the termination resistors are there.

The light PCB looks like a prototype or a pre-production unit. Cut traces and soldered cable make you think so.
The dark PCB looks like a demonstration unit. "D&P" could mean Demonstration and Presentation or Development and production, maybe ??

The ICs used are regular 74 series, so it can be easily copied. Even encapsulated in FPGA or so...

Any result on reverse engineering the controller program, by the way ?
