Sega Master System Power base
I popped open my Sega MS Power Base only to be let down. No sn76489 or Yamaha YM2413 for that matter, WTF? As it turns out there is a Sega 315-5124 chip which is a TMS9928 VDP ( a video sub processor ) combined with a SN76489 sound chip. Interesting, but where is the Yamaha YM2413 for FM synthesis? Well I guess it was an optional chipset on Japanese systems that allowed for 9 channels, 15+1 instruments, hardware vibrato and amplitude modulation. The board have traces for the chip marked. Damnit. Sorry to lead every one astray with the previous post about the Yamaha Chip, however this should set the record strait. One good thing that did come out of this is that I have a console that is naked sitting on my workbench. I think I may do a quick video bending tutorial with it.

hmm, ive read on a few sites that it has three tone generators, the psg, an FM chip, and some other one that was for samples.
psg wouldnt make much sense since some genesis games did have samples...

only the japanese sega mark iii had an FM chip.
The mark iii was pretty well equivelent to the MS in every other way.
