I am looking at the Tandy Service Manual for the Tandy WP-2 Portable Wordprocessor. The order number is 26-3930 - I seem to recall paying about $30 for this. It doesn't list the ROM code, but it does give all the pinouts, circuit diagrams, the IO address map, and an (inadequate) example of how to make an executable program, and a list of the ROM routine entry points. I, too, thought of trying to write programs for this - it would take an assembler and some way to download binary files, but that could be hacked together somehow. The killer for me was the stupid keyboard; the Model 100 keyboard was at least pretty decent (N-key rollover), but the WP-2 keyboard has not only 2-key lockout, but for fast touch typists (and I'm not all that fast), typing certains sequences of characters too fast, without letting up each key before starting to press the next, generates garbage. Try typing 'line', without letting up all the keys. I eventually ended up giving the machine to my wife and kids, all of whom want to do some typing, and don't go so fast, so that's no problem.
