Re: 29C/25C question. Message #7 Posted by Walter B on 2 Apr 2012, 11:43 p.m., in response to message #4 by Andrés C. Rodríguez (Argentina)
Grazias & obrigado for that old post and pointing to it.
BTW, the QRC of HP-29C contains a note on its very first page telling 'Primary storage registers, program memory, displayed X-register, and display format are maintained by continouous memory.'
And on page 9 of Getting the most from continuoous memory you find
'When you tum off your HP-25C, the calculator retains
information stored in the:
• 49-step program memory,
• 8 addressable storage registers,
• LAST X register.
Numbers in the stack are not saved. However, if you
wish to save the number in the display (X-register),
simply press a [ + ] or a [ - ] before switching your calculator
off. When you tum your HP-25C on again, press [ LAST X ] to recall that number to the display .'
Sometimes RTFM really helps, but also small printed matters contain valuable information ;-)
