6100 Computer Programmer’s Reference Guide
The PEN*KEY 6000 Series system, depicted in Figure BĆ3, is like the standard
desktop or laptop PC, except that a physical hard disk drive is not used for storĆ
age. Instead, a section of the RAM memory is defined as a RAM disk. The only
difference between the systems of Figure BĆ2 and Figure BĆ3 is the storage locaĆ
tion for software components. In a normal PC, this type of system would work
only if the power to the RAM was never removed. By its nature, the RAM
memory loses (or forgets") its contents when the power is removed. However, in
the PEN*KEY 6000 Series Computer, the RAM is powered continuously. ConseĆ
quently, the RAM disk retains its contents over long periods of time.

NOTE:
In the illustrations, 4- or 8-megabyte memory models are shown. Keep in mind, as the
PEN*KEY 6000 Series systems continue to be enhanced, that future releases may allow
larger memory models. The double-headed arrow from the “Application” to the “disk” indi-
cates that the application loads the data from the disk, then writes it back to the disk.

How the 6000 Series PEN*KEY System Works
In the system depicted in Figure BĆ4, DOS and BIOS are stored in the flash
memory. Flash memory is similar to RAM memory, except that flash memory
does not forget" its contents after the power has been removed.
