Musicmax gives an demonstration about installing and the use of the Commodore c64 Kernal Multiload. This device comes in two parts: One EPROM that replaces the original Kernal of the Commodore 64. And a control-box that makes it possible to select and start an alternative Kernal. In the video you can see that the SX-64, EXOS V3, JiffyDOS and the Cockroach Turbo ROM are being used.
