USB keyboard adapter, especially designed to fit directly on your Tides-Rider main board. It allows you to use a USB keyboard as if it was an Omega Keyboard.

Any USB keyboard should work, including keyboard with a built-in hub.

The adapter does a direct USB key-code to MSX matrix translation which fits the common ANSI keycaps on the Omega keyboard when used with an international MSX BIOS. Thus an American ANSI keyboard is recommended.

If you use a localized BIOS, a same language modern keyboard may better match what you see when you press the keys or not, because MSX used old variants of some language layouts and usually provided only one dead key.
