What is The Workstation 4?
Memory Architecture
The CF card contains the POS application and support files, a current copy of
the registry, and optionally application transaction data, or in other words, the
workstation ‘personality”. The CF card is accessible from outside of the
workstation, it can be removed, forming the basis of a ‘personality swap’.
Should a WS4 fail, the CF card can be removed and installed in a replacement
unit, giving it the same configuration as the inoperative workstation from
which it was removed.
Even though the Workstation 4 is diskless in the classical sense, the
combination of the Disk On Chip and CF card provide a mass storage solution
to preserve application and registry settings that require a lifetime that extends
across system reboots. Through the CAL, updates to the OS and applications
are staged on the POS server and automatically propagated to each client
