* VARCem Virtual ARchaeological Computer EMulator.

* With the EMS method, the system's standard memory is expanded
* by means of bank-switching. One or more 'frames' in the upper
* memory area (640K-1024K) are used as viewports into an array
* of RAM pages numbered 0 to N. Each page is defined to be 16KB
* in size, so, for a 1024KB board, 64 such pages are available.
* I/O control registers are used to set up the mappings. More
* modern boards even have multiple 'copies' of those registers,
* which can be switched very fast, to allow for multitasking.
