HP Integral questions

I've been reading the HP Integral service manual that Al kindly put on
Bitsavers , It's a strange manual in that it includes schematics of
the main logic boards. Why, I don't know, other comtemporary HP computer
service manuals didn't. Not that I'm complaining...
Anyway, various thoughts occured to me as I remember some
thignn about that machine
1) Did HP ever produce the CS/80, SS/80 or Amigo drive exerciser software
to run on the Integral? It seems it would be the ideal machine for use as
a drive tester since it's so easily portable.
2) The later version of the OS ROM module has a space for an option ROM
PCB. It seems like this would be trivial to recreate (schematics of the
ROM Mmodule, inclding the pinouts of the option board connectors are
certainly in 'my' Integral schematics). If enough people are interesd,
it might be worth laying out a PCB...
3) The manual mentions that the Integral expansion bus was an
implementation of some other HP standard bus, but only rows A and C. What
other machine(s) used a similar bus? I can't think of any.
 I've also been reading the HP9000/200 Pascal 3.0 system
docuementation. A wonderful mine of information, but oh so annoying to
read on a screen...
