Found this while looking for something else.
Downloaded Javelin Editor and that is a SERIOUS editor. Heavy emphasis on Debugging like SX Editor.
Where's the SX Blitz? Did it come out after 2004? That's a short time for them to totally disappear. Say if it came out in 2008 or 2010.
Guess there is some connection to today's Propeller 2 FPGA files.
