mark sells a shaker motor kit to fit new modern sterns as does rtbb and marco spec etc. I reckon it would easily be adapted.

the specs are the exact same for the shaker motors on data east and segas. buy one and get beaky to see if he can make it work etc. it does come with software and a computer board etc. if it works keep it, if it doesnt, send it back. 

i never felt my RFM needed a shaker motor, but it might be a great idea if u can get it to work. 

I doubt very much I could buy a stern shaker motor kit and send it back on the basis that it didn't work in Bally pin and I am not about to test this theory in practice.
