Just bumbing this thread, since it's a new year 😀. I hope that dreamblaster will find some time to start working on a new batch 😀.

Hi! Does the current revision decode one of the 8bit ports, like 0E0h i suggested? I'd be keen on creating a new pack of patches that works on 0E0h. I also don't mind creating an additional pack for the OUT 0C0h method, provided that there's already a TSR that hooks the interrupt, so i can test everything.

Mind you there is no "current revision". Dreamblaster has indicated they have little time to make a new batch, and though we're all cheering them on, there's no guarantee there will ever be a new ISA card with this sound chip. I'm not sure what the "old" revision decoded. C0 should be safe for PC/XT class machines (AT has DMA2 there), E0 could be safe.

I’m running a new batch now, so feel free to drop me a PM if anyone is interested. This helps me estimate the quantity.
The price will cover only my expenses, as this is a hobby project and I’m not making any profit from it.

Can you tell which revision this will be? I have a couple of your older ones...

Hi,

I just realized that I can make some improvements.
I had issues with the Eagle-imported KiCad files and also with different KiCad versions. For example, I couldn’t replace a part and update it on the PCB without losing all the net connections.

Since some parts at JLCPCB are no longer available to order, I also need to reorganize a few components.

So I decided to redraw most of the Card. This will cause a slight delay, but now that I have more experience than when I designed the card the first time, I can improve it further.

I would be intrested in one.. seems I do not post enough to be able to send PM's 🙁 I noticed a bit late so hopefully can still get in on one.

Thanks
