Prisma Megamix. New soundcard for classics!

[bubbob42]

@FastRobPlus: Yes, you need a clockport splitter in this case. Or a CPU card with additional clockport.

@spudje: you got it right - the Paula passthrough without the need for additional software has been working from the start, though

I'm holding off buying this until both CDDA and pass through audio from game floppy boot works.

They said they would make a insulated version and come back to us about it.
I just checked their webshop, and no such option.

I will poke Matthew via private messages on aw.net and amiga.org, but its a bit puzzling that they dont include such purchase options. Im sure he is loosing out on selling quite a few units this way.
Could I insulate such a unit myself? Yes, but Im willing to have it done for me for a price from the vendor itself.

You have to order it and state in the additional comment field that you'd like to have the insulated version. I don't know why that info has not made it into the item's description, would save them a lot of hassle...

[spudje]

I've seen people receiving their insulated version already, e.g. on a1k.org

@bubbob42: Thanks for the info. My bad then, I thought the passthrough for now still required some activation in software/AmigaDOS first.

@spudje

Yes, they probably end up loosing revenue this way.

Anyhow, thanks for the tip. Will order one right now

Recived my Prisma MusicCard (insulated) yesterday, and obviously dropped all my plans for that day, and barricaded myself in my Homeoffice (nerd den).
Read the little piece of paper that came with it, skimmed thru the Wikipage, just to make sure I didnt fry the card by doing something wrong, but the one picture regarding clockport installation is pretty much all you need to know.

So installed the card, installed the driver from the floppy, hooked up the cables (the Out in addition to the RCA passthru from the A1200 jacks/out).
Changed the AmigaAmp engine to prisma library, and it all worked instantly.

The Prisma card output very good soundquality without breaking a sweat while playing 320 kbps mp3s. Passthru works perfectly. Nice and crisp quality. I havent tested many programs yet, just AmigaAmp and Hippoplayer, but so far so good!.
Since Im using the A1200 for re-learning ASM coding these days, listening to tunes in the background while hammering away in AsmOne will be good fun

Whats missing on the Wiki, as Dan Woods/Kookytech pointed out in his youtube review of Prisma, is pictures of the pass thru from the Amiga, and a picture with labels of what each of the backplate connectors/plug ins does.

Overall impression: Very happy with the purchase! The MAS player was decent in its day, when 128 kbps mp3 files where common, but today, the MAS player is cripple hardware when lined up next to the Prisma MusicCard.
I see on Apollo Team channel some people are downgrading their movies to accomodate the current level of features of the Vampire to play the movie library they have. Same was needed to do if you wanted to use the MAS on a non Vampire Amiga. I simply refuse to waste my time converting movie and soundfiles just to play them, SO Im very thrilled that Amigakit sorted out the hardware bit music wise, just as Im confident Apollo Team with sort out the movie playback (to a reasonable level ofcourse, I realise there are limits).

I know FOL did mention he had tested Prisma on his A600+604n clockport, and it works. I do wonder if it works fine with a Vampire, altho I dont see any reason why it shoudnt.
I have read comment about the 604n frying Rapidroad USBs, but is this just hersay, or something that is an actual issue; either with the Rapidroad being overly sensitive or the 604n clockport being the issue....?
Im tempted getting a Prisma for my Vampire 600 too.

Is it possible for WinUAE to emulate the prisma megamix so tools using it will work under emulation ?

[lantus360]

since its just MHI, isnt there a CPU based MHI driver that would work with the same API as Prisma?

If someone tells me how the chip is mapped to expansion address space and if there are some interrupt enable/request bits or other IO registers. I am not interested in reversing new software or hardware.

[kamelito]

@FOL Can you talk with Matthew and maybe Trevor to see if you can provide Tony the info he needs to emulate the Prisma? It would be then easier to patch OS friendly games to support the card among other things...

Just give full access to the Master.

What are the four ports on the the backplate for? Is one port enough to have stereo output and one input port enough to have stereo paula input?

I figured it out. The leftmost port is enough for stereo output and the second port from the right is the paula input port.

[Retrofan]

Sure?. Maybe you are getting a double mono instead of stereo. I do think you need to use two mono to rca connectors and having the Amiga in front of you, two connectors on the left for Paula and same on the right for Prisma.

I want to know what Fol says as I'm not very sure.

[FOL]

Looking from back.

Left most port = Output.
Second port in from Right = Paula Input.

[ancalimon]

What is the first port from right used for?

And I wonder why there is a second sound output port? Maybe for headphones?

[Retrofan]

I think it would be better a photo with names of each thing.

[Pat the Cat]

Wow. Really really really nice bitrates happening. Software support always issue new hardware, you need both evolved. Done.
