This is a collection of small microcode programs to assist in debugging CP problems with a scope.  Most of them should work on both the DLion and the Dicentra.  On the DLion, they run in Kernel mode.  Use Burdock's LoadRaw command to start one.

Flap means make all the wires on a bus jump up and down together.  Spin means to iterate through all possible states.  Poke means to make each bit in a bus/field go up while all the others stay down.

BEWARE:

These programs assume that you can figure out what things should look like by reading the listings.  If you don't understand what's going on, be sure to look at a known good board before jumping to any wild conclusions.

HINTS:

In general, IB_ is a good place to sync on.  There is nothing magic about it.  It's just a signal generated at the top of the loop.  It isn't used for anything else and doesn't get in the way.

If things look strange, check for a ControlStore Parity error.
