Sequential circuits samplers

I have successfully replaced the disply in my Prophet 3000!!!  At 
your risk, I can give you info on what could lead to an equivalent 
replacement for the graphical display.  Not the original, mind you 
(backlight is green instead of blue), but what an improvement!!!  I'd 
need to check out the currently available parts and make sure of any 
minor mod's required, but I'm 99% sure it can be done.  It's kind of 
a long story, but I have one working using a display which is a bit 
older - I just need to confirm compatibility with the currently 
available displays...

Just how many of these are still in use anyway?

I posted a photo of the working replacement display in the "Photos" 
section of the Prophet2000 Group site...
