Sequential circuits samplers

I have checked the blank sample size, and it's +56. I read somewhere in 
the old posts that a 1-gig expansion gave lots more memory. What would 
the blanked-out memory size display read then? We are all probably not 
the original owners of these misbegotten keyboards. Musicians are a 
poor lot. They are always selling their gear, to survive, or to get new 
gear. These P2k units have bounced around for twenty years. You have to 
be a detective to even operate the thing. Once it starts, the thing 
just comes alive again. I am sure it is thanking us, like a orphan. I 
have opened it up, to find the O.S. It is 4.2  I was looking for the 1-
gig expansion board. I didn't know what it would look like. Does Wine 
Country ever show pictures of it? Just curios I guess.     ESW
