Protovision listed the PAL LumaTOLB at 25 EUR but temporarily unavailable with unknown delivery time on 2026-07-30. The current listing gives a three-year warranty and says the original timing chip need not be removed. Installation may require replacing the VIC-II heat shield with a larger one. A hands-on 2018 report says LumaTOLB does not work with C64 Reloaded MK2, although the separate original LumaFix does. No current NTSC order path was verified.
