HP29C Question



#2

I need some help with several HP29C related questions.

Unfortunatly I don't have my own so I can't check these myself, hopefully someone out there will have the paitence and time be able to provide me with some answers...

How does the HP29C calculator display instructions that use indirect addressing in program mode?

STO + i 23 51 22 or 23 51 15 22

RCL i 24 22 or 24 15 22

GSB i 12 22 or 12 15 22

Is the 'g' key stroke shown in the display as the instruction is entered? Are key strokes show as they are entered at all or does the HP29C differ from the HP25C in that respect? Is it necessary to press the 'g' key at all - what happens if you do?

Thanks.

On the 19C and 29C, the 'g' in sequences such as STO g i, is optional, and in program mode, it is not shown in the display -- so STO i is displayed as 23 22 on the 29C and 45 12 on the 19C.

Thank you - as ever you are a very useful source of information.

Of course I really ought to get a Museum DVD or better still the real thing but I'm not allowed to spend any (more) real money on this particular 'hobby' ! :-(

I'm sorry to hear that you're so strapped for cash, but then again, fortunately, there are plenty of people on this forum who are happy to answer questions like the one you asked a few days ago.


I used to own an HP-19C myself, back in 1978-79, and whenever people start talking about the 19C or the 29C, this brings on a happy wave of nostalgia. :-)

It isn't the 'cash' she is worried about (or at least I hope not!) she just doesn't approve of me wasting money on things she regards as unimportant/trivial.

If you are interested I may/should have something in a couple of days that should be able to induce on 'a happy wave of nostalgia' that I can send you via e-mail (and given our previous exchanges you can proably guess what it is!)...

Unimportant? Trivial? Blasphemy! You need to take revenge and veto her next shoe purchase. ;-)

Sorry, I can't, but feel free to surprise me!
