1 OVERVIEW
General
This model has the performance equivalent to an IBM-AT machine which uses the Pentium •as a CPU.
This model has its unique functions added to it and is provided with an ETHERNET circuit and touch panel as standard. The
desired system can be built by adding various optional functions. Its display is of 800 x 600 SVGA specifications (standard),
using a color LCD. It is provided with a 20-digit x 1-line or 2-line fluorescent display tube for customer display. In addition, it has
an interface of up to 2 channels for a Cash Drawer.
