That makes sense and I understand that production overruns between 2 models can and probably did happen.
I've seen S+ machines dated 1996 and 1997, so I thought it odd to find an S2000 dated the same year as the previous model machines.
The speakers are pretty neat, all metal construction unlike the plastic ears found on most of their other products. Probably won't ever find a replacement speaker like that one. The missing bottom speaker is kind of a bummer, not as good of sound quality as the enhanced audio of the 3 speaker system.
The speakers were probably a trade off, get rid of the costly metal framed ones and add 2 cheaper plastics and a subwoofer.
As far as the rest of the internals, it's pretty much all S2K.
Thanks for your input. I'll probably hang on to this one for a while. I may search out some IGT training videos and see if I can spot another cabinet like the one I've got.
