Yamaha YDG2030 EQ Interface IFU495 QS1 Software Info Help Wanted

Hello,
I am trying to find some discontinued Yamaha Products

I have an old rack of Yamaha YDG2030 EQ's in a Monitor Rig
They use to make a RS232 to RD485 Interface with QS-1 Software to
control them via a computer/laptop but it is now discontinued.

Anyone have one of these that they want to part with ?

Or anyone have thw software that maybe I can by an aftermarket
converter to get this to work ?

Finally Anyone try the C-Mexx C-console software ? It is Midi Based
but will only control up to 6 units.

Thanks for any and all replies/info
