I copied RPN from the lif disk to the 71b and started it with "run rpn" The first one is the RPN calculator from John Baker (file size is 1038 bytes). There is only one keyword, "RPN" - so just type RPN [End Line] and it should start the calculator program. [f] [ON] exits back to BASIC. For the 2nd one (started by RUN RPN) note that the program stores the X, Y, Z & T registers inside the .bin file, so while it does preserve the stack across different sessions, it also means that this RPNLEX file cannot be stored in EPROM (or FRAM configured as ROM/EPROM). The 3rd one (C71) is indeed the most robust, but as JFG has noted, it's impossible to get working on a machine w/o the extra modules, however you can check it out using EMU71/DOS or EMU71/Win. I'm looking into a possible source for having extra overlays made, but no progress so far. I'l be adding an extensive write-up on this 3rd one in the coming weeks. --Bob Prosperi |
