Title: Prisma?
Post by: QuikSanz on December 05, 2015, 07:49:44 PM
Here we are 2 years later and no news. Maybe in the year 2525. What's the problem guys? Waiting for all the old machines die with their owners?

During AmiWest presentation Trevor said; hardware done, but software still being worked on.
"feature creep" etc. "One more feature/optimization. Or somesuch.

If it is available then of course :laughing:

Yes, because Amiga users always find something to complain about. ;)   But it just seems like at this point they'd want to start recouping their costs for the hardware; and who knows, maybe if they started selling the cards the software would get done even sooner - think of it as all of us being beta testers. ;)

But what do I know? :laughing:

It seems there's a few teething problems with the CDDA header! Could be a deal breaker although since my A4000T video/audio module already mixes the CD-Audio then I guess it's not so much of a big deal for me?

Prisma Music card review by Dan Wood/Kookytech;

I watched this the other night, I always love Dan's videos :)

It's a real shame that the Prisma driver software wasn't ever stable enough when I was adding Primsa support to my ports...it would have been an ideal music solution for classic games (great quality music for little CPU load).

What could have been :(

What he could do is connect the CD Audio header to the A4000 motherboard header, since the Paula Audio connects to the Prisma header anyway.

True, but the A4000's motherboard header has a weird, non-standard pin layout.  I did make up a special cable to fit it a few years ago, but it was very unbalanced, CD audio was very quiet and Paula output really loud.  Will be much nicer when the Prisma does it, I imagine.

Post by: Oldsmobile_Mike on November 17, 2016, 04:34:05 PM
I watched the video and two of the three things I was hoping to do with the card don't work for him. So much for a three year wait! :(

Also - painful watching him open that box with scissors. For the love of god, get a utility knife! :p

Which 3 things do you want to do with the Prisma card?

The card project is still ongoing, including driver development, so those areas might be covered down the line.

List the ins and outs and we'll see what can be done with it.

Nah just saying that it took them too long to get it stable :(

I also updated my ODAMEX port to use Prisma but had to rollback the changes before release.

Oh well, now that they've got it running properly maybe someone else can start adding Prisma support to games.

Yes that is true the A4000 CD audio volume on the header is known to be low, some speculate it was so CD Music wouldn't be too loud over SFX in games.  There are however two easy fixes.

https://groups.google.com/forum/#!topic/z-netz.rechner.amiga.hardware/f3Lh-RwYJbU

Replace resistors or AsimCDFS lets you play the CDDA without the audio header at all, but I'm not sure if that just renders it via Paula.

@amiadudeorwat (http://www.amiga.org/forums/member.php?u=15955)

Not sure how that's possible? I too had to adapt a 4-pin PC CDDA cable for use in my A4000T. It was required for mixing the 2 audio streams despite having AsimCDFS. I'm not an expert however and was just glad to get it all wired up. The volume of the mixed sound sources are ok and match each other on the A4000T. I hope Dan can make use of the adaptions you suggest for the A4000.

Post by: amiadudeorwat on November 19, 2016, 12:59:32 AM
The playing audio without the cable with AsimCDFS I'm quite sure just  renders it down to Paula audio so it probably sounds bad compared to CD  quality.  This has been a feature on Wintel machines for a long time (and apparently some Amiga CD player programs) it just sends the CDDA over the IDE or SCSI bus, but since it's digital it has to go through Paula to make it out to the speakers.

The resistor method is kind of a pain, as the second  resistor is on the bottom of the motherboard so it means complete  disassembly, but if that's not a big deal then it's simple enough to  do.  

All that being said the Prisma should support this  feature.  It is to me a minor scandal that such a simple feature doesn't  work out of the box.  Maybe the wiki should be updated under the -CDDA  header (Yes it's there, it doesn't do anything currently).  

With the four connectors on the breakout, maybe one of them is a secondary input and the CDDA could be connected that way?

Back  to the years old discussion on this, I understand *It's not a sound  card, just a multiformat decoder* since WAV is one of the formats it  supports, why couldn't AHI be adapted to send WAV encoded audio to it?

Amiga 1200 Prisma Megamix Music Card Review with Surprise !

Title: Re: Prisma?
Post by: Oldsmobile_Mike on November 22, 2016, 10:05:35 PM
Has anybody figured out what the four headers on the breakout card are, yet?

1 - Input from Paula/external RCA jacks to mixer (if it works, as evidenced by the previous video it only seemed to work on one channel)
2 - Mixed output to speakers
3 - ????
4 - ????

That, to me, is a "minor scandal", that after three years of development they missed something as obvious as documenting what the connectors are.  :(

An interesting review and it is great to see game support for Prisma.

The customer purchased the Zorro Big Box edition of Prisma - a separate A1200 desktop version will be coming soon which is insulated for use within an A1200 case and includes a clockport cable.  This was announced when we made the big box version available for sale.

Agree! If I can't hook it thru my sound card it's no use.

If you have a sound card like an SB128 or an FM801 you probably already have Paula connecting into the line-in of this card.  You could route the speaker out from the sound card to the line in of the Prisma.  Or connect the speaker-out from Prisma to the line in of the sound card.

The issue Dan was having of only one channel working is probably just a bad solder joint or a dodgy connector somewhere, bad luck that it went to someone that would post a review.

Some documentation of those extra two connectors would be nice.  Maybe they do nothing and are for future expansion.

I wonder what was specifically wrong with the sound quality of the Paula pass-through? He didn't specify. Does anyone know?

CDROM out to CD in on Repulse. Prisma out should go to Aux in on that card.

Will it also work with A600 equipped with clockport, for example 604m?

Just finished doing another test. It works fine with A604n on a 2MB Chip unexpanded A600. However don't expect anything else without upgraded CPU and Fast RAM.

For anyone, who decides to try this. If you connect card clockport cable in the wrong way around, you are fully responsible for any damage. Remember clock port is reversed on A604n compared to that of an A1200.
