Quick HP42S question

I won't go so far as to guarantee that the RNG in Free42 will produce the exact same sequence as the real HP-42S, but I believe the algorithms are the same (see https://www.hpmuseum.org/forum/thread-9556.html for an earlier discussion, including a link to the article where I found the algorithm). I tried comparing the Free42 RNG to Emu42, both starting from Memory Clear, and they returned identical sequences as far as I could tell... I don't remember how long I let the test run, whether it was hundreds or thousands of iterations or more. At what point do you see a divergence?
