It's configuration is as follows:
|CPU||KN02-BA V5.7e||MIPS R3000|
|Clock Speed||20 MHz||-|
I do not have the proper cabling for keyboard/mouse, but when the framebuffer is removed the machine comes up nicely to the console prompt from the seiral bus (the connector marked with a "3" is used as console on this machine). In the self test it complains about the missing mouse/keyboard. I guess the keyboard/mouse connector should be terminated properly rather than just removing the devices.
