OK, according to , Prosthy Plus includes the stories of "In the Jaws of Danger" (1967) and "Getting Through University" (1968). "In the Jaws of Danger" was supposedly published in "Worlds of If", as I mentioned above, but, according to Amazon's online reader, "robotoid" is on pages 111, 132, 134 (along with "Metallica"), and 139.  confirms that "robotoid" appeared in at least "Getting Through University" (""Robot-sixty-eight per cent." The robotoid took the news impassively."), but this is from the 1985 TOR publishing of the book as Anthonology so I don't know if it also appeared in the original 1968 publishing (it probably did but it's not definite in my mind yet). Regardless, it's becoming more obvious Beter wasn't the first to use "robotoid". However, it's possible he never heard of it before 1979, assuming he wasn't into sci-fi or ever saw Lost in Space (assuming "robotoid" was ever used on it, as I describe above). -
