How common are 128kB MoonSounds?
I… think mine is expanded, but to be honest it’s been such a long time ago I have a hard time recalling 
.
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.
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.
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... 
Well, if it's any consolation, the 1.0 version they sold in the Netherlands was much the same
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
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 
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...
I remember I asked for money for my birthday so I could buy a MoonSound. A nice and boxed one with a gold label .
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.
