I never understood why that was a thing, Doug, do you know the rationale for bit pointers? The ETA-10 is not well known, I was part of the Lachman group: https://en.wikipedia.org/wiki/ETA10 My first job after school, I got to watch Neil toggle in the bootstrap stuff at the console. He wasn't Seymour but he was very very good. One of the more substantial people I've ever met, I would guess he has passed but if he hasn't, he would like this group of people. Whatever, Doug or anyone, why do bit pointers make sense? Why?
