RE: HP-25C Eumulator
Greetings! I've been working with Chris Chung on transferring the NP-25 project. For better or worse, I've volunteered to be the goat, er, rather the transferee. I just received my first NP-25 kit from Chris and built it up in about an hour. Turned it on and it worked (good sign). If I've done this right, there should be some pictures of my work attached to this message. I've begun ordering some small quantities of parts from the supply houses. Next task is to order the pc boards to make certain I've got the files correct and that there aren't any issues when the pcb's arrive. Please be a bit patient, to keep prices the same, most of the parts are on a slow boat from China. I'll continue to take orders (kit and assembled). The prices should remain the same unless Sparkfun runs out of displays or the pcb manufacturer goes crazy. I've got a TI Launchpad and I'm working to understand Chris' code and be able to modify it, if needed. I'm coming up slowly on this end of the firmware, but the current hex code will be easy to just download into the MSP430 and keep going as the project is currently configured.
If you have any questions, don't hesitate to ask. I'll lean on Chris for the tough questions, when he has a moment to answer. Cheers! Jim Johnson - Carmel, Indiana USA HP Calculator Collector |
