[sdiy] Inside a Roland Dimension-D or schematics?

[Synth-DIY]

Hi guys!

Does anyone know what's inside a Roland Dimension-D? Schematics would be great!
My buddys and I had one that was stolen and I'd like to see if it was possible to
recreate the effect somehow.
We had it patched in the feedback loop of a delay and it sounded so beautiful. 
Is it a very slow chorus, fixed phase-shifter or what?
