Recently acquired a Pioneer LD-V6100 (PAL) and the interactive training discs it was used with.

It's a big hefty beast of a machine (there is a picture in the database here already) - very like the LD-V6000, but with an extra couple of inches at the base to accommodate the MSX(?) cartridge port and the extra PCB it's on.

Unfortunately I have no documentation (posting this partly to plead for that), so I have no idea about its more interesting features, which include the aforementioned MSX slot/board, a video/audio input (2xBNCs + phonos) on the back, and an additional socket labelled "IEC-625" (complete with its own set of DIP switches) as well as the standard RS-232C serial port.

I've been trying it out, it's noisy (the cooling fan runs continuously). I don't have the RU-V6000 remote (assuming that's the one for it), and was annoyed to find that the remote from its "little brother" the LD-700 doesn't control it. I downloaded remote codes for my Logitech Harmony for it which do the basics.

But, disappointingly, other than having tried out the serial port (which works, but the codes seem very different to any other Pioneer), I haven't yet made it do anything more interesting than the LD-700 can do. I tried inputting video into the inputs - no effect. I have no idea at all what the MSX part does, but it's a very big circuit board with loads of chips, so it must do something...

Here's a photo of it, if anyone can make any deductions based on that - the cartridge slot is at the top left:

If not, I may pop to the MSX forum and ask there...

I've also been trying to get the MS-DOS software discs that were part of the interactive package working, but that's a whole separate saga which I may post about later!

So really I'm after a Service Manual, and any thoughts people might have about the video input and the cartridge port...

Sounds like it is for carts with LII code:

Thanks, that's interesting! Never heard of "The Videodisc Monitor" magazine...

It still raises a few questions though - an internal teletext encoder? That means, I guess, it can generate the little dots in the vertical blanking interval so that a TV can display teletext pages... but what would be the point of that? If a disc needs teletext, it can be added to the disc, as with the "BBC Videobook of Garden Birds". Do they mean a decoder, so teletext on a disc can be displayed on a video monitor not equipped with teletext?

If the latter, that might make sense of the video input - perhaps it could decode and overlay teletext on a signal being input there? Although I'm not sure what the industrial/educational application of that would be...

The remote illustrated appears to have the same key layout as the RU-V6000, but some of the markings look a bit different... it's not possible to make out the model number and the button labels on the original photo?

On a tangent, are there any Level II PAL discs about? I've dipped into the 'educational' and 'industrial' sections of the database here for PAL discs, but haven't spotted any mention of ones with LII code...

There is more information on it in Videodisc and Optical Disk Update, Volume 5 1986: https://search.worldcat.org/title/10367036
You can see if you can get access via British Library On Demand.

Yes but the same goes for LII dumps. If the cartridge slot allows for the overriding of LII dumps, seems like teletext being changeable makes sense.

Good eye. Looks like the LII related buttons are different. Here is a link to a higher quality image. Still hard to tell

Interesting question. I do not have any, but I would think that a 12" PAL GGV would have a dump. That would probably be harder to find than an educational or non-consumer title with one though.

By the way, I posted about this in the MSX forum - it has provoked a modicum of interest, the thread is here:
