Describe the bug
Seems like it might be possible to essentially set a "breakpoint" where the Apple II wants to scroll the screen, and preserve the line that's about to scroll off in a (capped) history log. I think the relevant line might be around:

fc70: a5 22        [SCROLL]()      lda     [WNDTOP](https://6502disassembly.com/a2-rom/OrigF8ROM.html#SymWNDTOP)          ;start at top of scrl wndw

Should of course handle 80-column text as well.
