Sound Blaster on Speccy
ZXNet echo conference «hardware.zx»
Hello, All
Please tell me if it is possible to connect Sound Blaster from PC to Speccy for
using MIDI and ADLIB?
Hello simens
In its pure form, no, because each type of card must be initialized by
to your own. But those cards that are loose (where OPL3) are quite suitable for
picking . It's more difficult with the MIDI interface, because... everyone has given up on standardization
. I propose to concoct a type like in the MSX turboR GT, they use a pop
UART and a programmable timer, both of which are produced by our industry. I
I was also actively interested in the topic of other UARTs, but all of them are no longer available
reachable. There are still single-chips with UARTs, but there will be a specific one
crap with standardization and firmware (every year something new is released, and
the old ones are not produced).
Hello simens
I’m not a super-specialist in this matter, but I can still say: Sound Blaster -
it’s kind of like a separate type of sound card, of which there were (and are)
a lot. The spec has its own SoundBlaster (by AlCo), although this is completely different
“device”, or rather an adjustment to the speck according to the principle of minimum parts, maximum
speed (in the sense that for most of the frame the program can do its own thing,
That's how I understood it, at least).
Let the pros talk about why it’s impossible to cut out PeeCee’s sound system (I even
I don’t know what to assume, but if you haven’t done it yet, then it’s impossible
for some reason - probably).

What is meant by "structure"?
Hello, Vladimir Kladov
Vla> if you haven’t done it yet, it means it’s impossible for some reason - probably
Very old cards (ISA-8) can be trimmed. With ISA-16 it will be more difficult, but with
PCI is generally unrealistic (within the framework of the surrounding reality) to cut down. And
You can use it (if someone writes the software). And they didn’t cut it for a reason
incompatibility of sound chip registers with AY/YM. In general, for the same reason,
that the video cards were not cut off either. In addition, during ISA-8 there were a lot of
incompatible sound cards. But in general, IMHO, this is not necessary -
why drag rubbish from another platform.
Hello icebear
What is meant by "structure"?
I think it's a map of registers and their functions. And under the "description" there is a breakdown.
Hello spensor
It makes sense to connect MIDI/PCM chips from mobile phones (YMU759, YMU762), but the docking
programming is hard to come by during the day, but Yamaha squeezes them.
I'm even ready to pay for such a document (a little :)).
We need a structure and description of the internal registers of the chips, I have datasheets.
Hello, CHRV
CHR> You need the structure and description of the internal registers of the chips
Not a “fountain” of course, but I think the datasheet from YMU757 will do. This chip is from the line
MA-1/MA-2/MA-3, which corresponds to YMU757/YMU759/YMU762. In the downloaded document
(search quickly) there is the necessary programming information.
Hello simens

Yes, all FM generators and sound processors (from SB) have this capability.
It is stupid to write bytes to ports only in the Covox and Beeper systems.
Hello spensor
CHR> MIDI/PCM chips from mobile phones (YMU759, YMU762)
And in which (what generation/old age) mobile phones are they found?

I know, but this chip has a serial bus and not enough channels. By
Apparently the register doesn’t really match :), it’s a pig in a poke
reluctance.
Hello, CHRV
I connected an 8-bit soundblaster like this in 1998, but my experiments didn’t last long
lasted, they squeezed him :v2_cry:
Hello Orionsoft
I was rummaging through old ZX Reviews and came across an article on the topic.

Hello, Jukov
ADLib - it can connect and is possible, the only question is where to get this
museum...
