You have read the thread starting with
news:<6o3et1F1lkamU1@mid.individual.net> in news:comp.lang.c? It
completely confirms this.
<speculation>
For the background: It might be that Commodore thought there might be
uses of the MAX, where there was no need for the CIA. Thus, instead of
forcing the use of the CIA - which takes up some address space - they
decided that a cart might decide to disable it, and use something
different (VIA, PIA, ...)
</speculation>
Regards,
Spiro.
