Chipper is a toy assembler for a toy language called Chip-8, which is a video game interpreter commonly found on RCA CDP1802 based home computers in the late 1970's. Chip-48 emulates the original Chip-8 instruction set precisely, except for the calling of CDP1802 routines. Super Chip-48 V1.0 and V1.1 extend the instruction set of Chip-48, in order to utilize the higher screen resolution of the Hewlett Packard calculator, and also provide a few additional features. This package includes the Chip-48 assembler to run on DOS and the C source code.

UNRPL 0.04   (details) 48 ENG   21KB
Standalone RPL decompiler for decoding RPL threads in the history of Voyager from Derek S. Nickel and SAD from Jan Brittenson in the early 90s. But Unrpl use a different approach, as it isn't an expert system like the other programs for decompiling a complete ROM image; it is only a very simple decompiler running for all RPL platforms. This is the big advantage of it, as it can decompile RPL objects from one of the first generation RPL platforms like that used by the 28C to the latest RPL generation introduced with the 49G.
