Even then it was not universal. For example, that Apple I ad that got posted a few days ago mentioned that "the system is expandable to 65K".

Someone here the other day said that it could accept 64KB of RAM plus 1KB of ROM, for 65KB total memory.
I don't know if that's correct, but at least it'd explain the mismatch.
Seems like a typo given that the ad contains many mentions of K (8K, 32K) and they're all of the 1024 variety.
If you're using base 10, you can get "8K" and "32K" by dividing by 10 and rounding down. The 1024/1000 distinction only becomes significant at 65536.
