3.14 Is there a way to tell if an HP 3000 has a floating point co-processor installed?
WARNING: Only use these methods with great care since HP does not officially support them.
SYSINFO will tell you this. Run sysinfo.prvxl.telesup. The command CPU, for SYSTEM CPU MAP, while show the status of any co-processors. For example,
CO-PROCESSORS:
FLOATING POINT COPROCESSOR IS INSTALLED.
or
CO-PROCESSORS:
NO COPROCESSORS ARE CURRENTLY INSTALLED.
You can also use debug (per Stan Sieler):
= ccr
$c0
If the left two bits are 0 (they’re both on in my example), you have no arithmetic coprocessor. On some machines, you might see $80 with an arithmetic coprocessor.
