Makers of 128k ram boards are not going with bank select, but are
using linear addressing as per the IEEE-696 (proposed) standard
because it is much more reasonable - in terms of simplicity, in terms
of on-each-board hardware, in conceptual terms, ...

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.
