CompactFlash Cards (Models 602 and 603)
Main Memory

megabytes (MB) for the model 601 and 16 MB for Models
602 and 603. Memory and the real time clock is protected
up to 72 hours by your computer shutting down operation
after detecting low battery.
Flash ROM
The 512K Flash ROM stores the BIOS.
CompactFlash Cards
Your Industrial Mobile Computer employs an internal card
slot. The internal slot is a CompactFlash Type I storage
device. This device acts as the boot drive for the system.
This CompactFlash card is not externally accessible.
Additionally, Models 602 and 603 provide an external card
slot.The external slot is an expansion Type II slot. This
Type II slot is accessible at the top of the computer. It can
be used for an additional CompactFlash storage card, or a
CompactFlash modem. A modem card must provide the
RJ-11 jack. However, since part of the modem (because of
the RJ-11) extends beyond the top of the unit it becomes
vulnerable to breakage if dropped.
