My experience in accidentally loading P50 code into a P130 (after the loads diverged) led to my feature request for having the boxes reject inappropriate code loads. (For the curious: a P130 will run P50 or P75 code, but it loses all it's config so you have to reconfig via the console port to recover.) Also, there's now a P85 in the same box; the P15 looks different.
