    Yep, the software that shipped with the Phasor included a simple
diagnostic test. It's on side one of the first disk, just select option '5'.
It detects what slot it's in, does some basic I/O checks and performs 
an audio test (tone generation, white noise and speech). If you can't 
find the disks online let me know and I'll send them over.

    My Phasor was dead when I got it. It turned out the 74LSxxx chip
was blown, and swapping in a new one fixed it. Make sure the DIP
switches are set to Phasor-mode (both should be closed) and turn 
the volume pots up. 

Dug up one of my old posts from 12 years ago, this may help too:
