D550 processor

2010-08-11 by PeWe

Hello !

I�m in need for a D50/D550 processor urgently.

RL-15179266 D78312G-022 - MASK ROM CPU ( for Ser.No. 15179266 or up)

Roland germany passed and Vintage Planet removes it rom their list now, 
it�s not in stock unfortunally.

Is this a orignal Roland made processor or is it from another 
manufacturer ?

Anyone here who can help ?

thx

PeWe
