Setting switches for a Vertex 150 possibly for a perq

[Chris Zach]

Hi!

I'm trying to read possible Perq2 data off a 40mb Vertex V150 drive. 
Unfortunately the switches were scrambled and I can't seem to figure out 
which settings work. Does anyone have one that can check their switch 
settings?

This doesn't seem to work:
