commodore4ever LUM-FX 64 Ultra

commodore4ever built ULTRA has the ultra small footprint!
 
Redesigned to have a smaller footprint and cleaner design, the LUM-FX 64 helps to remove stripes, green/red lines or a checkered pattern that mostly appears on modern output devices via s-video. It has three toggles to adjust the video signal (and shield it from other signals that are also present in the VIC-II), thereby improving the picture quality.
