Prisma Megamix. New soundcard for classics! - Page 24

Ahhh...sorry, my bad.
But now something else is happening. After pressing Return (in CLI window),
Cursor is going one line down and there is no prompt at the beginning of that line and I just cannot do anything (the music has not stopped).

What does the PrismaPlay.guide say? Example scripts included? If not write a script like:

Code:

/*example*/
trace i
address "PrismaPlay"
"stop"

Start it with rx and see if the output helps. If not ask the author.

There is nothing about it in documentation - I just found it in that thread - maybe it has not been even released yet...

Anyway, here is the result:

If there is no documentation about it than it it could be possible the ARexx port isn't activated/finished. As far as I know they are still working on the driver. Best option is to ask the author. http://eab.abime.net/member.php?u=41191 if I'm not wrong.

Just try it, you can't damage anything - if you don't connect it the wrong way around, that is.

Before I connect things up, can I just check I have the orientation correct?

http://www.e3b.de/usb/index_e.html

Using a clockport cable, I connect white tab on prisma to '20' on the Deneb? The Deneb faq shows that '20' is equivalent to pin 1.

http://wiki.amiga.org/index.php?title=Prisma

The prisma faq says "On the Prisma's PCB, there is a white square printed next to the clockport header which matches where the red key wire of the clockport cable plugs onto the board."

Hmmm, this is where it gets tricky, and you should really confirm the details with AmigaKit. My take on it is as follows: the Prisma has pin 1 at the top left as you see it in your image, marked with a large white box. That is connected to pin 19 of the clock port when used on an A1200 (see image here). From the image of the Deneb there, it *looks* like the Pin 20 marking correlates with pin 20 on the A1200 (pins 19 and 20 are the power supply pins and you can see the thicker traces and decoupling cap), so I would say that that does indeed count as pin 1 when dealing with the Prisma.

Other cards do it the other way around however, marking pin 40 as pin 1, so it's always good to double-check with the manufacturer before you try it.

Thanks for the info Daedalus. Good shout on speaking to Amigakit, I'll do just that

bubbob42 · 03 May 2018, 23:33

Just take a Multimeter and check for electrical continuity between the outer pins for each row of clockport pins -

those:

Code:

  -> .xxxxxxxxxx. -<
     xxxxxxxxxxxx

or those:

Code:

     xxxxxxxxxxxx
  -> .xxxxxxxxxx. -<

find the row where it "beeps". Find that on the other card's clockport. Check again. Then check AGAIN.

Then connect the cable so that the "beeping pins" of the cards are connected to each other.

Is it possible to get the firmware for the prisma card ?

I have to get mine repaired and need to replace the Xilinx chip..?

Thanks

arti040 · 07 November 2019, 11:22

Seen this? New, cool GUI for MHI, which supports Prisma Megamix as well!

Overmann · 21 November 2019, 09:25

Is there any info about availability? I can't find these anywhere.

trixster · 21 November 2019, 09:39

I don’t think they make them anymore which is a shame as they’re great. I can’t really understand why there was a fair bit of negativity about this card when it was released.

Daedalus · 21 November 2019, 10:52

Yeah, I'd like one too, but they seem to be only rarely available second-hand these days.

Looking in to it. Just have a few other projects on at the moment, as you may know,

Daedalus · 21 November 2019, 12:22

good news!

kriz · 01 February 2020, 17:22

Yeah we need this card for sale again please .. !! Also @arti040 Where can i get that new MHI GUI program, all links seems expired at that forum ...

Predseda · 01 February 2020, 18:43

I have had a good talk with Matthew at Amiga Ireland meeting two weeks ago and I have a good news - Prisma Megamix should be available in its new version this year.

E-Penguin · 02 February 2020, 08:25

It would be great if they offered AHI drivers for it

Overmann · 02 February 2020, 08:49

I thought there were AHI drivers for it!
