68000 and upwards was the spec I was given, so that's what got written. :) It does mean you can use a vanilla A2000 to play high bitrate compressed audio as a jukebox, though, and that is kind of cool!

The VS chip is not designed for computers at all - it's designed for embedded hardware like, strangely enough, MP3 players :) However, it is a very funky little chip, as long as you can keep it fed.

I've played with all sorts of mechanisms for keeping the data flowing freely, and I figure that anybody with such a loaded system that a VBl will cause instability will have at least a 68040 anyway, the two systems I have should work just fine. For people who don't like IRQs, that's why we have the delay loop version.

We did consider a buffer but it would have complicated the hardware design markedly, and it does work as it is. I know this because I just listened to it playing. :)

Put a Prelude in my A2000 while they were available, late 90's. Good stuff.

BTW, Update?

MHI Driver Working!

A driver was developed to let programs which are MHI compatible use the Prisma.library and playback through the Prisma Megamix music card. I am pleased to confirm that it is now working with AmigaAmp on the Classic Amiga.

Here is a screenshot of Prisma in my A1200 running AmigaAmp, using the new MHI driver:



Thanks to Spirantho for his hard work on this driver.

@amigakit

What Arexx commands are already built-in?

Is any guide for PrismaControl's Arrex available?

Regards,

Needs some nice way of mounting in A1200 original case.

Brought this out of the depths, Are we going to make these again? I can use 2. Or will this just stay dead?

@QuikSanz

Wow! I didn't think they'd sell out! Good for them! I never managed to get my question answered as to whether you could run the Rapid Road Clock Port version off the additional clock port on the Prisma. Oh well

Will they ever do the addon for adding cdrom audio output to the Prisma megamix card and line in as well?
as this is a great card apart from no cdrom audio input
