there's some kind of additional maths DSP, likely with internal ROM.
(it's not actually a standard MS32 PCB set, just uses the same hardware + extra chips)
I was actually send some pictures of the hardware and struggled to match up the roms with the pictures tho, which was annoying because I was trying to identify exactly which chip the DSP was likely to be.
very little has been 'completely forgotten'
