Yamaha SPX 900 - has anybody heard of this?

[SoUlGuY]

I came across an auction which includes an old Yamaha SPX 900 processor. I've tried searching for information,reviews and specs on this machine but no luck.

Does anybody know about this machine? Is there a URL on reviews on this processor?

I'd appreciate any feedbacks on anybody who have used this unit.

Thank you in advance.
