RE: HP-25C Eumulator
Hi Chris,
yesterday I received the PCB. Thanks a lot! I have installed the LEDs, a CR2032 and switched it on - with no success... Seems like the switch has not survived in the mail. Maybe you can protect that with some extra padding for the next shipments. Anyway, after replacing the switch everything works fine now Which brings me to my Questions: The simulator always comes up as a HP21 when I turn it on. I worked out that by pressing <g>, <sigma+> or <Clx> on power up I can switch to different roms. But is there a way to make the selection permanent? And also is possible to save the program in flash memory? Cheers, Harald PS: I am really impressed by what you have done with Erics nonparail here!! |
