If anyone is interested I have reasonable photos of the board in question (both sides of the board).

Well, if you already have the photos, feel free to upload them!

All I have is random photos from the web that I can't upload here and photos from this forum.

Yeah I guess just uploading them won't cause any harm. Here you go.

Hello everyone, friends, I am very interested to make this board. About half a year ago, I started drawing this board, but I don’t have enough information about some of the connections, if there is such an opportunity, I can call the connection and you can check the multimeter. And also I will forgive you to give me photos in very good quality from different angles.

Welcome to VOGONS, kompas-rus and thank you for the photos, gca!

You should be able to derive a lot of the connections from a combination of the reverse-engineered Adlib schematics (here), the manual of the Game Control Adapter (here) and application notes from the datasheets of the TDA7233 and LM324 amplifier chips.
Since I don't own the original card, this is all I can contribute for the time being. My KiCAD files are linked in the first post, but as you can see, they do not contain any traces, yet.

Adlib, friend is an example circuit, but it doesn’t fit in the area of the decoder, I also look at the SB1 circuit and the SB2 circuit that I drew, but this is only "GAME PORT" from 558. I need more, I won’t do it fast.

Please give me a photo of the board in good quality, I need to make silk on the board.

You were interested in the address decoder portion of the card, right? I ran into similar problems with a few connections that were obscured by the components, but I have since been able to figure them out via re-engineering.

This should be it:

Friend, this was done 6 days ago, I'm interested in "SILK" to maintain the authenticity of the board, I can not write PM.

As usual, you can use one of the general threads (e.g. 'what retro activity did you do today?') to gain some karma, so you can so PMs.

Friend i don't wanna do spam
Someone write to this person in PM, say that I will forgive a photo of good quality. Re: Clone of Amstrad's Adlib clone

I have relayed your request.

The answer is that the card is currently installed in a system that is stored away somewhere and that taking additional photos would consequently involve too much work.

Besides, I'm not exactly sure what exactly you cannot see on the existing pictures, particularly the ones in the thread that I linked in the initial post.
Are there any component designators you cannot read?
Unless you in all seriousness try to import the raster images as silk-screen, directly, the existing photos should be adequate.

The quality of the photos presented here is poor, I can’t copy "Silk", I tried to find a nice font, but I can’t find it, I think it would be better if the photo is in good quality, I can make a perfect map clone, I did it many times before .

Unless I find any errors, this is the finished design:

The routing and silk screen are similar but not identical to the original because I found them ugly.
There's obviously no Amstrad brand logo on it, either, and I've shifted the DA15 connector in a position that is compatible with Keystone bracket 9200-3.

The first batch of five PCBs it on its way.

Benedikt But this is a bad clone of the card, I would like the appearance of a 100% original board. I also ordered 10 boards, but I will have them in February.

It is a trade-off between a good clone and a good card. The original card looks like the person who created it didn't even care about clean routing and well aligned traces. The data bus, for instance, is all over the place.

The other modifications are practicality-related:

• Smaller hole pitch for most electrolytic capacitors – The original was using 2mm pin pitch with 5mm hole pitch, which just looks awkward
• The DA15 socket has been shifted by a few mm, because drilling two holes in a DA15 bracket is easier than creating a new bracket from scratch
• The footprint for the audio jack has been changed to that of the switched version (more pins), so that you can populate it with whichever version you can get your hands on

As I said earlier, I found the routing and silkscreen ugly, that's why I tidied them up while keeping the overall layout largely identical.
If you have a different taste and prefer a 100% accurate replica, that's obviously equally legitimate.

In the end of the day, independently creating two different accurate replicas of the same card would be kind of pointless.

I think the changes make sense. Especially making it compatible with the Keystone bracket is useful. Getting custom brackets is a pain in the behind. If I didn't have so many homebrew soundcards already, I would build this one as well. 😀

The changes make sense, good looking project !
