Patches and discussion for Ensoniq VFX family

I had a similar problem with my Sept. 1991 SD1 about 3 years ago.  
The solution I was advised to try was to unplug the SD1, open it up 
and CAREFULLY disconnect and then reconnect each of the spade lugs 
connected to the power supply.  This has the effect of scraping the 
contacts clean and reseating them at the same time.  After closing up 
the machine I did the hard reset (turn on then immediately off as the 
display lights up for 7 repetitions).  On the last power-up it worked 
fine.  Had to reload the OS, etc, but it's worked fine ever since and 
it's still on it's original battery.
