HP 48 Cartridge

Description:Document explaining a way to upgrade the HP 48 using a NVRAM, Non Volatile RAM (that is, it still keeps data even when there's no power) of 128K from Texas Instruments Corp to make something like a external cartridge. The great advantage of this is that these NVRAM chips can be obtained for free, as TI has a samples program.
