BTW, if you're running 9.00 or later, on hardware that was released in '92
or later, you can use the model(1) command to get an expanded model
string. For example:
 $ uname -m
 9000/829
 $ model
 9000/829/K400
Here are the mappings for older HP9000 Series 800 machines:
 Model number on the String returned
 outside of the box by uname -m
=============================================
 default ----------> 9000/800
 E25 --------------> 9000/806
 E35 --------------> 9000/816
 E45 --------------> 9000/826
 E55 --------------> 9000/856
 F10 --------------> 9000/807
 F20 --------------> 9000/817
 H20 --------------> 9000/827
 K400 -------------> 9000/829
 F30 --------------> 9000/837
 G30/H30 ----------> 9000/847
 I30 --------------> 9000/857
 G40/H40 ----------> 9000/867
 I40 --------------> 9000/877
 G50/H50 ----------> 9000/887
 I50 --------------> 9000/897
 G70/H70 ----------> 9000/887
 I70 --------------> 9000/897
 G60/H60 ----------> 9000/887
 I60 --------------> 9000/897
 T500 -------------> 9000/891
On earlier machines, "9000/800" was returned by "uname -m" when HP-UX
could not determine the model number of the machine. This generally
indicated that the machine was not properly configured.
On more recent machines (As, Rs, Ls, Ns, etcx..), "uname -m" ALWAYS
returns "9000/800." To ascertain the machine's model string you MUST
use the model command.
