For those with investments in older BS (Band Select) software, Godbout and others make a memory mapper which maps an I/O port onto the upper 8 address lines; this seems to have the effect of making bank select software work with modern RAM cards. I can't swear by it as I don't have any such software around. Ian Darwin Univ of Toronto
