The BTX module has been sold in bigger quantities. 
So, taking it off the cupboard will enable to use it as extended GFX card.
And again: it put it signal into the video cable of the CPC - So, NO two monitors!

Any more info on what the BTX module is?

But not much is know about how it works. It could store BTX pages locally and display them again, but it's more likely that this was using the core text based data. I would definitely not expect that you can send pixel graphics at an acceptable speed to it.

Looks like a basic subtitler type hardware

It's like a GFX card. It has it's own CRTC (the same as the CPC actually) and RAM.
I found out how to program very fast high-res / high-color GFX by disassembling it's ROM.

Information in the net is scarce:

Show us a demo... Because I will be impressed if it can display more than a Minitel. :)

Do you have the BTX module? Then I can post you a DSK.

Today you can make Youtube videos with any mobile phone. Maybe you know someone who owns one.

Could you please post the disk? I have a BTX module somewhere around and can do a video.

Awesome! At 2:55 the high resolution GFX can be see!  :) :) :)

Not at all. It is displayed by the CPC.

Any thoughts on the Agon Light just released? If you watch the youtube about the Agon Light they talk about the separation of the VDP and the rest of the computer - seems the VDP is serial driven and perhaps could be the basis of a CPC gfx / sound card?

Apparently prototyping used the following and this could perhaps make a reasonable gfx card for cpc, any thoughts?  Might also be able to get a mouse adapter from it.

Basically a $20 graphics card plus shipping plus soldering the serial port to it, makes it a LOT cheaper than a v9990.  And I suspect still pretty useful.

I'm curious to see why you have chosen this and how you will connect it to the CPC.

The idea of using the VPD9990 comes from MSX world, because they do use the predecessors, so the 9990 (should be / is) compatible to the previous Video-Chips.

It's may also be useful in CPC world when someone ports a MSX program written for the 9990 to the CPC world. Or if someone particularly makes software dedicated for it.

However the best result for new GFX cards for the CPC can be at least one of two ways.
- Having a primitive GFX card, but being able to be used memory-mapped
- Having an intelligent GFX card

In every case the new GFX card should imho be able to mix the 'new' signal with the regular video signal. An example is the previously described BTX module.  :)

I totally agree, but until thenwill see what happens - even my Amiga can't do that, so I need to manually switch the TV between HDMI and Composite - in the CPCs case, it would be manually changing the TV between VGA and RGB - not ideal but workable and does also support 2 monitors also.

the ESP-VGA32 is useless for this... it only produces 27 colors just like the CPC.. (it says 64 but most the colors are duplicate or mixed with background)..and the colors dont match cpcs colors..
also theres only like 3 spare gpios on it.. hard to connect it to cpc without a bunch of other supporting hardware...
it is good for emulating the entire CPC with room to spare...(if ya dont mind the off colors)

No, it's not compatible.

That's a pity. But I hope it's not too far away to convert classic MSX software to it. Metal Gear on CPC would be nice.  ;)

My X-CPC 2020 design provide extra screen modes:
- 640x200 with 4 colours
- 320x200 with 16 colours
- 160x200 with 256 colours

I may think the do a graphic expnasion based on it if enough free time next year.
