We use the Periscope III debugger here at Graphics Software Labs and love it.
You can trace back through the last 8K worth of instructions, set hardware
breakpoints on code, data or I/O.  In short it is the best debugger I have seen or
read about for the PC or AT.  They can be reached at 1-800-722-7006 (or for those
outside the US 404-256-3860)

I have no affiliation to Periscope other than as a satisfied customer.
