Although the HP Portable+ Technical Reference doesn't contain anything on 
the physical disk formats, there's a table in the usner manual for the 
FORMAT comamnd (I've changed the headings a bit, but the data is the 
same) : 

Specifier  #sides   Secotr size   Capacity  Files in root dir
/w           1       256          264192         128
/x           2       256          618496         304
/y           2       512          700416         176
/z           2      1024          780288         96
none         2       512          700416         176 

The default seems to be the same as other HP MS-DOS double-sided disks.

I wonder if Chuck (I think) got a disk formatted wit hthe /z option from 
a Portable+ and sassumed it was the defualt?
