Ken Pettit has a complete disassembly of the ROM in his personal files on club100. And if you can get your hands on the books "Hidden Powers of the TRS-80 Model 100" and "Inside the Model 100" they are good programming books. You're going to need a cross assembler. TASM is what I use but it no longer seems to be available. I can send you a copy. You might be better off with asxxxx cross assembler though because I think that is what Willard uses and he actively maintains header files you can use. -- John.
