Here are a couple of things to try:

1) Turn the K2 on.

2) Be sure the rtc menu item is on, per page 18 of the KDSP2 manual.

3) Turn the K2 off.

4) Turn the K2 on again, then press AFIL (hold the XFIL button rather 
than tap it).  Depending on mode, you should see CF1, CF2, or SF1, SF2, 
etc. on the display.

5) If you get the expected CFsomething, SFsomething, or RFsomething 
(depending on mode) then U1 is operating properly and the DSPx may be at 
fault.

6) If you see "not inst" then it means the K2 and U1 are not 
communicating. This is not a DSPx problem.  It is most likely an auxbus 
issue, and I'd carefully double check the 2N3906 location on the KDSP2.

Let me know...
