Roland 700r wanted

Hi I have a roland vs 700c without the interface (vs700r) Does anyone have one for sale (I live in SW Scotland UK).
Alternatively can anyone advise me on using the vs700c with an alternative interface- will it work properly- what are the issues?
I realise this is an old piece of kit but I own it and would like to use it.
Will it work with Platinum?It seems to work OK with X3.
Any help Much appreciated
Thankyou
