My MoonSound XM converter+playroutine thing is gradually starting to produce sound output that resembles music, and I began to wonder what would be a reasonable RAM target or "minimum spec", for a music disk or something. How many MoonSounds are there with only 128 kilos of RAM for custom samples, any ideas? I guess many people have expanded their MoonSounds during the years. Though on the other hand, maybe it's a good idea to have most songs work with 128, and then have a few bigger ones.

I… think mine is expanded, but to be honest it’s been such a long time ago I have a hard time recalling Smile.

I would try to target 128k if possible. It’s nicer to just say “MoonSound supported” in stead of having to add all kinds of conditions to that support.

Mine has 640kB, but I only used it once (for my Italo challenge song.

Like Grauw said, target 128kB and consider any extra RAM a nice bonus :)

Only 1st gen Moonsounds (connector on top) are likely to have that much RAM installed, no ? The newer ones are so easy to expand I doubt people would keep using them with 128KB ...

version 2.0 had 128 by default... It was until around the turn of the century they came default with 1024... The guys still around will probably have some more than 128 though... The 128 units are probably somewhere in a box on the attic...

I was mentioning that 1.0 had it's sample RAM chip soldered. 2.0 RAM was on a very nice round pins socket. Smile

Also it had a nice cart box. 1.0 was a fugly bare board, too. I know mine was a 1.0 with "box upgrade" from Sunrise itself.

I mean they took a pile of scrap from a corner of the bench and build a couple of Moonsounds then sold to us here in Brazil... Wink

Well, if it's any consolation, the 1.0 version they sold in the Netherlands was much the same Smile

I received mine without a box (as was usual at the time) and received the box later. It was a bit clunky; they drilled a large hole at the top of the cartridge box so that you could plug in the audio cable. It was always trial and error, finding the connector and inserting the cable without breaking it. So I modded mine with a bit of cable and a nice headphone connector on the side Smile

I know the 1.0s... By that time the Philips modem cases weren't there yet... Therefore the hole on top of the case was drilled to fit a complete jack plug going totally inside the damn thing Big smile
And indeed, they had not foreseen a memory expansion like the 2.0s... Though, the 2.0s can be expanded rather easily, be aware that not all RAM pins should be plugged into the socket... Seems there's still a design flaw in 2.0...

At the time I made my own OPL4 board I sold the Moonsound. Because the OPL4 was using Philips' I2S (http://en.wikipedia.org/wiki/I%C2%B2S) as protocol, I ended replacing the sound DAC with a Burr Brown PCM1710U chip and a simpler audio output. I also experimented with a Sanyo LC78815 (that is what the Brazilian Shockwave uses as DAC).

My board has 512KB becase I wanted to be able to play Omega's stuff (at the time it was the songs with bigger sample banks) ...

I remember I asked for money for my birthday so I could buy a MoonSound. A nice and boxed one with a gold label Smile.

I think the real question is, would using more than 128k really add value, and fulfill a musical need. I would start with a target of 128k, and then only increase it once you realise you need more and you can’t fit the sample in another way.

I bought a 1.0 MoonSound second hand and got it expanded to 640kB by Koen (and also get a new casing).

At some point Wolf set a standard of 640kB minimum. I guess he used it for the Infinite trackmos.

I think (partly) due to this, Sunrise also started selling them with 640kB or 1024kB (IIRC, that was their last batch). It's on some Dutch fair photos.
