Are there any #MC68000 #mc68k gurus in the audience?
If a program running in usermode accesses the vectors via a data access instruction - what does the 68010 indicate on the function code pins?
Are vector reads escalated to being supervisor code/data reads, even though the code which triggered them is user-mode?
I'm trying to figure out why dereferencing a null pointer is 'fine' on a real #UnixPC but causes problems with the FreeBee emulator (if I disable vector access promotion).
