Akai S1000 / S1100 samplers

inside of it - I only do know that the Akai S950 had an Intel
compatible (186 IIRC) processor for the main tasks, would love to know
(and hear) if the Akai S1100 is still based on such a (compatible) CPU
, or is this a completely custom made machine which doesn't run on
anything but custom ASICs ? (From what I've read it includes custom
ASICs, however it seems still somehow unlikely that such a vintage
sampler is completely customized already.. only Ensoniq/Emu did that
efford from the "emulator-4 based "(e4k/e6400,etc) machines on..

The reason why I'm asking is because I want to develop some software
for it - and this would simplify the process tremendeously - I do have
all the necessary tools at home (EPROM burners, logic analyzers,
scopes,etc)

So far I have only snatched this rather low-res picture from the web
of the internals... I suspect (and hope) the rather lengthy chip in
towards the center on the front could be the CPU..

Many thanks for a quick reply in advance,
