I can't remember if the original 8x2 machines could boot from SCSI.
Their immediate predecessors, the 8x5 machines, couldn't (but the
ability was added later via a firmware upgrade).

That aside, 8x2 machines are a slightly older version of PA-RISC
(1.0? 1.1?).  The 9000/7xx and most newer 9000/8xx machines are
running newer versions of PA-RISC (1.2 or later).  The most
important difference is in floating point instructions. 
The PA-RISC kernel *could* be easily compiled for 1.0 architecture...
I doubt that it does much floating point work in the kernel!
Further, it could be compiled with 1.2 scheduling...that still
works on 1.0 machines.

The I/O architecture is HP-PB, like the 8x7 machines, so that
may be okay.

If it turns out that the current port won't work for you, you
have a few choices:

   1) wait for it to be done, and modify it for 8x2.

   2) use your 832 with HP-UX.  You can go to 
      and get HP-UX 10.20 for free.

   3) trade it for a machine supported by the current porting

If you opt for (3), you may want to know about the Classic Computer
mailing list ... a worldwide group of computer collectors.
To post a message to it, send to:

The 832 is a 30 MHz machine.
