Patches and discussion for Ensoniq VFX family

I have a VFX-SD (it's really an SD-1) that I got as a loaner.   There is one patch on it that 
seems to cause the 129 fatal error.   All the other patches seem to be fine.   It does some 
other funky things, like sometimes you have to turn it on and off a few times before it 
boots up OK.   Hey it's old.   

Anyway, I was wondering if there was anything I could/should do to make it run a little 
more predictably...   

Thanks in advance...
