You are watching an EPROM with the last version (Ver. 1.3) of the operative system of a Kawai K5 synthesizer. You can check the ROM version simply by watching the screen during the boot process - the version will be displayed in the right bottom corner (check picture). There are many improvements over previous versions - specially over version 1.0, mainly related with SysEx transfers but also some improvements in the interface.

This is not suitable for the K5m model. If you need the EPROM for the K5m model (Version 1.2), just contact.

My EPROMs are equipped with a UV proof label.
