Details from Francois – This product works well on all C64, C64c, and C128 (1 Mhz and 2 MHz). also works perfectly well on the Ultimate 64, and it does support higher operation speeds up to 48MHz. Although the Ultimate 64 does already have GeoRAM emulation built-in, you still have the benefit of battery backup with CleoRAM. 


CleoRAM (and GeoRAM) compatible applications are: 


GEOS 64 (with appropriate Configure), GEOS 128 (with appropriate Configure), Wheels 64 (with Toolbox update), Wheels 128 (with Toolbox update), CP/M, GeoRAM Digi (C64), Funkpaint (C64), Volley for Two (C128) and the tools at
