Does anyone happen to have an SI and SI deluxe side-by-side, OR do you happen to know if the sounds are slightly different? Seems the missile sound in Deluxe may be faster/shorter than the normal SI, just curious.
 
I don't have each working at present, but I can tell you.....the sounds between the two are a little different. They each have a different sound/I/O daughter card. Now, it isn't uncommon to see a Space Invaders Deluxe daughter card on a Space Invaders motherboard.

IIRC there is one capacitor value that is different in the missile shot sound between
SI and SID. I think the other sounds are all the same. The input strapping is different.
And the bit shifter circuit/implementation may also be different (there are several
layouts and/or custom chip options).
