I disagree that a plug-in ROM module is 'loaded' in the normal sense. The BASIC firmware is not copied from
the module into RAM. The ROMs in the module are directly accessed by the processor to run BASIC, just as
they are when the ROMs are on the main board of the machine.

Does that mean you should remove machines where the BASIC ROMs were socketed, on the grounds they
could be removed?

Incidentally, are you including handheld computers: HP71B, HP75C, HP75D, Sharp PC1211, PC1500 (and more), 
Casio (dozens of models)?
