No.  It is not yet upgraded to a P5.1.   I just want to see If I can
format it as 8 heads 1224 cylinders for the time being.

It does not boot.  With the diagnostic disk in the floppy drive, and the
drive connected, the UNIX PC just keeps putting rows and rows of those
little rectangles across the screen.  (I only let it make 3 rows before I
gave up.)

Thanks, I plan to get Lenny and s plans and board(?)

I did get some mail from a helpful soul who has this drive running on
his UPC.  He described the SW1 settings needed.  I will try this,
and post results for future reference (if it works! :-))
