Just received an Amiga 2000 motherboard

Hi, You could buy an adapter for the power supply, or find a guide how to convert the the power supply to Amiga. http://wordpress.hertell.nu/?p=282
When using a non Amiga PS, there is a J300 jumper that switches a TICK clock. http://www.l8r.net/technical/t-2000-jumpers.shtml
FYI, Composite video is in Black and white, so don't worry if something looks odd.
The Mb will work w/o keyboard or battery.
They have mouse and keyboard adapters you can get, and use PC style accessories.
Having a keyboard and a front LED will aid you in troubleshooting if things don't work. When there is an error the CAPS LOCK will blink number of times, and Front LED will dim during reboot.
