Mas Player Batch



Hi:
I was thinking to make a mas player. For what I've heard the more difficult part is to get the chip. I've seen this: http://www.snailinstruments.com/eng/mp3chips/ 'MAS 3507D' .

Is it the the one needed?

Hmmm...
Looking at http://eab.abime.net/showthread.php?t=19439
The chip is a 3507D G10
The one on your link is the 3507D F10

Not sure what (if any) is the difference between G and F for that chip...

From the MAS-Player webpage: http://www.mas-player.de/cgi-bin/mas...e=mp3_hardware
...it doesn't seem to require any specific subversion of it.
On the materials list it says only MAS 3507D 44pin so I guess it's the same as the one you linked.

It's also nice that it has option for extra QFP44-DIL44 adaptor board that is full of win for making a custom board with it without having to SMD solder 44pins

Ok. Now I only need someone to make it....
I've sent some mails asking for it. The first was to Amigamaniac time ago (4 january), and he told me ":-) I will look into is a.s.a.p. to see if it > is within my (limited) ability :-)".
But now I'm adding that link with that chip too.
I've been asking to others too.
I think there must be a couple of people interested in getting one.

You can find the chips on ebay 24 euro. Maybe kipper2k can make some, I think there are a lot of people with intrest. Count me in for 2.

The best is that this cost $9.90. I will ask him too.

For those that don't have an idea what Mas Player is:
http://translate.google.es/translate...s-player.de%2F


And just to be clear: With this small board connected outside your Amiga you can play MP3's with any Amiga, forgetting about an expensive accelerator or a problematic sound card.



Edit: Here's the info to make it: http://aminet.net/package/mus/play/MAS-Player

"MPEG hardware for the AMIGA
~~~~~~~~~~~~~~~~~~~~~~~~~~~

Hardware based MPEG audio decoder for the Amiga printer port.

What is MPEG audio?
MPEG audio is a compression procedure for audio data.
It is also well-known under the names MP2 or MP3.
It is possible to reduce music pieces to a data quantity of approximately 1/10
by this procedure.
That means, a music piece of 30 MB size shrinks to 3 MB without a loss of
hearing quality.
With this comparatively small data quantity, it will be attractive to play ones
music pieces on the computer.

Why a hardware for decoding?
The Amiga of course is also able to play MPEG compressed music pieces.
However each Amiga has still the old custom chip "Paula" on the motherboard.
This audio chip is only able to produce 8 bits.
But if you manipulate the software, it produces 14 bits (with approx. 27 kHz).
However to achieve CD quality during playback, a 16-Bit sound card and at least
a 68060 processor with 50 MHz is needed.
PowerPC owner (like my fewness) will sneer to this problem because they have
enough performance available.
However most Amiga owners have still an older model located in the corner, which
can be converted with few expenditure to an MPEG Player.
The advantage of an Amiga computer is that it can be attached to each TV set.
Thus it is possible to select the titles visualy, and to place the Amiga for
example near the stereo system.

For whom is this circuit suitable? This circuit is suitable for all who want to
convert their old Amiga with small expenditure to an MPEG Player.
Because of the hardware based decoding a standard 68000 should be sufficient.
But it would be better to use a 68020 or higher in my opinion.
A sound card for the Amiga is not necessary, because the DAC (digital analog
converter) on the circuit fulfills this function.
Playback takes place with 18 bits at 44100 Hz (CD quality).

Which Amiga computer are compatible?
This circuit works with all Amigas, which possess a parallel port.
My software addresses the port chip (CIA 8520) directly to reduce time.
That should not cause problems, because all Amigas possess this chip (except the
Amiga clone "Draco").

In the case someone ruins his Amiga, I AM NOT RESPONSIBLE FOR ANY DAMAGE!
Anyone who is stimulated to tinker, solders on his own risk!

Much fun with soldering!"

Hi,

It should be possible to make a small batch of PCBs, sourcing the components would be tricky as MAS3507 and CS4331 are obsolete. Ok you can purchase the MAS3507 from a few sources. Might be possible to use the newer CS4338 Stereo DAC as a replacement. This would require a tweaked output stage.

The other tricky component might be the 3.5mm audio jack.

Manufacture and assembly of a batch of PCBs from one of my suppliers is £20 per unit.

Now it's up to you, developers/manufacturers. I've asked to Amigamaniac (1 month ago), Fol & you (yesterday) and kipper2k , in that order.

As I told you it was sold very expensive at the time, 59 the cheapest or 83 euros even; but the chip alone was 45 too. A cheaper batch would get a hundred of buyers, I'm sure.

Our new project is very mature and almost ready to go. It is an evolution of Mas Player.

I would like to know more abour this player; if it can be used as a sound card like the Delfina and if then it has an integrated sound mixer or if it just will play mp3's and so.

EDIT: I've received today a mail form Amigamaniac and he's telling he is planning to make them too (after my request, a month ago EDIT!! It seems also Steven in Australia (AbraXXious) asked for the same thing too) as he's found the obsolete chips new and very cheap...

It will play MP3 perfectly on an A1200, and has a pass through for the normal Amiga audio. So you wont need to mess with the audio wires.

The prototype works very well. If Amigakit is ok, with it. I can post pics of the MAS Player Evolved.
