The Extended memory is treated like the cassette in the way that
you access it. It is in a different part of memory than the "main" memory.
The "overlaying memory" comes from somepeople modifying their systems
to install their own memory. You must be carefull when you do that.

The cassete drive MUST have the HPIL interface.

You can upgrade to a 41CX which has most of the memory built in 
plus extended functions plus the timer. 

Having the card reader or the cassette is usefull because you can archive
programs for other people and other places.
