I'm no expert on MSX but I like them a lot.
I still wonder when I look and read about different cards.
GR8Net, Wozblaster, PlaySoniq and TRH9000, could such engineers as the creators of these particular cards do a "brainstorm" and jointly design one card containing all these projects in itself, is it even possible?
Card that would have NET, all sound cards, SD support, video 9990 and 16MB ram? There is a possibility? Cool

My price is 100USD, cost is around 70.

No problem! I have signed up! What time slot do we think of? First quarter this year, or later?

I just want more people using MSX...

Me too! I would also like more people to get hold of an OPL4. And maybe if we program some real good games for it (which includes some awesome OPL4 music ofc), it may get more people to buy the OPL4.

I signed up as well. What kind of cartridge shell will you use?

If you check the article I mentioned previously you will see that I have two cases. The first one is based on a custom 3D model I created and fits the original Wozblaster board created by Gustavo Iriarte. The initial 10 cartridges I built were based on that board.

Then I made a custom board that can fit in a traditional standard MSX cartridge case. The new one is smaller and have holes to fit both Konami and "patola" cases we have down here in Brazil.

Here is the version with the custom 3D printed case:

Here is the version with the traditional case:

Everything is available on the github repo and the article I mentioned previously.

@crisag I signed up here, https://theretrohacker.com/wozblaster but I did not get a mail or response. Was it really registered?

Okay, looks good! Maybe it is a good idea to add a photo to the reservation page?

Thanks crisag for your hard work.

I also contacted to MSXCalamar and they told me that didn't have more chips to build new ones and they were waiting for more, but I didn't receive any news.

I also contacted to antoher MSX builder and told me he had problems getting OPL4 chips.

Finally I posted here to see if I could get an old one, and after some weeks, crisag contacted me Running Naked in a Field of Flowers

You are on the list Bengalack. I'm delivering the first 10 and will start working to ship to the ones on the list. I expect to contact everybody in the upcoming days/weeks.

I signed up as well. I do like the original 'guitar amp' cartridge design more; do we get to chose either design or not ?

That one is the default moving forward. I used the violet custom case for the first 10 cartridges as I used the original PCB, which doesn't fit in any standard MSX cartridge case.
