Yeah, I was thinking between MOVE and MATH, why would you ever need an OUT box anymore?, but wasn't sure if you kept one for old school guys. Personally, I'm glad to be rid of the thing. Working on the 405 when I was used to the 505 made me want to pull my hair out, between the accumulator, octal, and BCD, especially BCD. Oh, and no K-Memory and no forces (at that time).
