It is possibly an in house generated assembler. It may even have been written in Forth. Most Forth assemblers are written as single pass but it is not hard to make it a multiple pass. Such an assembler could have been cobbled together in Forth in a couple weeks of one programmer. I do know that they did extensive internal work in Forth. I have a ICE product that was clearly done in Forth ( missing pods and personality floppies ).

I would suspect it was the Rockwell System 65 Development System assembler mentioned in this book:
