DMA sound (that's what it's called in the doc)

Hello, Eugene

21 Mar 98 Eugene Safronov chewed his fingers in the hope that Roman
Milukov would read about Sound on Speck. Re:GMX controller, I
read this and decided to answer:

So this is the DMA controller

Why, you guys threw this circuit into
ZX.SPECTRUM more than six months ago, I have all the documentation for it, the circuit and the sources
of the Mouzon MOD player, I even wanted to assemble it but I didn’t find
the “airplane” and therefore spat :) there in the info it was written that
the printed circuit board is already being developed, and you just
snapped up to make it and launch it into the world? Damn yougive!

Sincerely, Andrey.

Hello, Andrey!

And this is my first time I've heard about this. :( And I’ve been with FIDO since November last year. And if they had made a board, I would have made it for myself. I don’t want to go on an airplane. It will be big. And if you immediately make a slot for a writing multicard in the board, then you can have a screw, a flop at
1.44, and plug in an external modem. Of course, I don’t know how to use it there, but they connected the multicard to 461.

All the best.
With respect, Roman Milukov.

it this document is also there, it’s dated 23-12-97.

By the way, in the same file sheet there is a dock, trdos firmware, for connecting
multicards to the spec.

Firstly, this type of sound card was developed by several people, I
know three types. Who is the author of the one you have a document for? Secondly, the other day I
personally
spoke with the author, he did not part with the payment, he gave the go-ahead for us to do this.
Secondly, has everyone already done this map, and we just woke up? You
didn’t have a “plane”, the other “fish” just died?
And GS is gradually diverging... It may soon become a standard.
And we brought to light a more powerful thing, with direct access to memory,
has a good sampling frequency and sounds very good!
I don’t know what you saw in ZX.SPECTRUM, I’ve been sitting there for a year already and the likes of me didn't
come across (maybe I looked it up?).

Hasta la vista.

I greet you from the bottom of my heart, Roman!

Wed Mar 25, 1998, Roman Milukov squeezed the keyboard, hoping that the following words would reach Andrey Isaev

If there is information, how to make a slot, so that later you can plug everything in,
make it mono, if you would like... We are waiting for 461, for some reason they are not visible :(

But no, it’s a crappy way, you can’t connect a screw or an external modem. Only
flops.

Yes, they have some kind of problem. :( They say that this echo hasn’t reached them yet. I don’t
even know where it got stuck.
And about the slot I asked there. They say, the same thing, that you just need to connect a screw - 4
buffers, an address decoder and a couple of small logics you need - that multiyahu. But then
it becomes possible to connect good flops and an external modem. I’m even lost
- is it needed?

It’s strange, there are already troubles at the entrance to 461 echoes, strange...
As for the cartoon, I don’t care, the main thing is that it’s connected.

No, they just delayed it for a long time, if I have a docket using exactly the
card that you make, then it (the docket) came out a long time ago.
TK> it was, the other “fish” - and it died?
In our 5026, I was the only one who wanted to do it.

It’s too expensive.
TK> I don’t know what you saw in ZX.SPECTRUM, I’ve been there for a year already
Personally, I didn’t see anything there :( in those distant times I didn’t have a feed, and everything
that was thrown at us was downloaded by one Amiga and it reached us already in
processed
form.
