XRGB-1

The first device in the line of XRGB upscan converters. It has four dip switches for changing configurations, and potentiometers to adjust colors and brightness.

Dip switches

Values	Description
15 kHz / 31 kHz	Adjust output scan rate
NTSC / PCB	75 ohm / 220 ohm setting
FM Towns /Normal	Special setting for FM towns computer
Normal / Narrow	Control aspect ratio (*)

(*) note that only V2.2 PCB has DIP switch for Normal / Narrow, the V1.1 PCB only has three DIP switches.
