For example, if you install a 64KB RAM module into port-1, it must be 'freed' in 32K ports

Both the CMT and HHP 32k modules have a signal pin that corresponds to the Last-Chip-In-Module bit in the FRAM71 configuration nibble. It's possible to open the modules and reconfigure how the LCIM pins are connected to create RAM ports greater that 32k. There is a bug with the 1BBBB firmware and 64k ports, so be aware.
