Does anyone happen to know where to find the manual or additional info on this calculator? I found very little info on this site, but that was it (http://www.calcuseum.com/SCRAPBOOK/BONUS/15091/1.htm)
The electronics seem to work, but the printer only feeds up to a certain point, where the paper is right below the ribbon. Then it stops feeding even when I press the up button. If something is wrong with the printer, I admit that I don’t know where to start with troubleshooting it. The metal parts that push the ribbon against the spinning numbers also don’t move at all, but the two plastic wheels spin the ribbon around.
I’ve tested all configurations of the switches above the keypad, and I can’t seem to turn off the printer either. That probably is just a result of me not knowing how to use it though. If anyone has troubleshooting advice or even just ideas on what sources to use for further research, it’d be much appreciated!
That calculator only has “NP” labeled on the top right switch, but I saw another similar one that had the other setting labeled “P”. What is that switch for? It’s really funny in the context of computer science.
Probably no print?
Edit: Snippet of another calculator manual
So no proof of
P != NP. Too bad.I couldn’t tell to be honest. It didn’t have a very obvious effect, but I didn’t figure out how to use it yet. I think it’s my first RPN calculator which complicates things a little bit.
