Description The C120+4 was essentially the same as the C120, but came an additional 4mb of RAM. If the device appears to be a clone of the Casio handhelds of the time, consider it was manufactured by Casio, with the only difference being slight color changes in the casing.
ROM Upgrade Details Both the C120 and C120+ had the capability of being upgraded internally to CE 2.0 via rom chip replacement. By the time the C120+4 was shipping, CE 2.0 had become the standard, though a very few early releases still carried the CE 1.0 ROM chip.
