The Hyosung 1800SE Mother Board Assembly (also referred to as the Mainboard or Main Control Board) is the central processing module for the Nautilus Hyosung 1800SE ATM. In the "SE" series, this board is distinct from earlier models because of its smaller form factor and use of a 3V coin-style battery to maintain NVRAM.

Core Versions & Part Numbers

Depending on the manufacturing date and specific terminal configuration, the 1800SE typically uses one of the following board version.

WinCE 6.0 Mainboard (Standard for 1800SE):

o Part Numbers: S7650000053 or S7650000167 (New Revision).

o Design: Much smaller than the WinCE 5.0 boards used in "CE" models. It is typicallyinserted into a larger I/O Board rather than hosting all ports directly.

WinCE 7.0 Mainboard (Modern Integrated Version):

o Part Number:S76500000289 or S76500000338

o Design: Introduced as a later upgrade; it integrates the I/O board into a single larger assembly and features three USB ports on the side
