What 6502 macro assembler was used for the AIM-65 Monitor ROM?

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 ).
