Patches and discussion for Ensoniq VFX family

I downloaded the O.S. ver 2.1, but the sequencer does not load.  The 
system just halts when loading it.  I looked inside the board, and 
have chips marked 2.0  Is there a big enough difference between ver 
2.0 and chips 2.0 to cause this problem?

Thanks!

I have both 2.00 and 2.10 on disks if you need a copy.
