Sequential circuits samplers

Thanks, it worked.  I replaced the 1N5401 diode with a 1N5402 and now
it turns on and seems to function as normal.  Now to upgrade the OS,
memory, and add outputs (I have serial number 80). I have a friend who
has a memory expansion board and OS IC (mine is 3.0) and I think I'm
going to try to get him to trade for my s900 then I can install the 8
outputs.  Anyone looking to sell anything?  I would hate to have to
deal with Wine Country.  

By the way, I can not get the Prophet to format disks.  I suspect
because I don't have single sided disks (I am giving it DSDD) and it
keeps saying nD (no disk).  Any source on single sided disks or any
suggestions on drive upgrade?  Can it be done, what drives, etc?

Thanks,
Chase
