So, what's the story?

With respect, I think the conversation has gone something like this:

You: My new Ford won't start. Ford are such a pile of $@%"*%&! Us: You do know you have to press the gas pedal when you turn the key? You: Ford are such a pile of $@%"*%&! I'm getting a Volkswagen!

If you aren't prepared to listen to advice then it's your loss not ours...

Some devices are too challenging for certain users.

Even simple things like trimming replies is too challenging for certain users.

The guy's evidently a troll. Let's close this thread.

Don't do that !!!

Send them to me, and I'll check them out myself.

Just one final thought for you. All the posters who have been posting in this group since it was created claim an extremely good success rate at booting Raspberry Pi's straight out of the box using a random selection of PSUs and SD cards, with known and repeatable problems due to marginal makes of card and out-of-spec PSUs. You are the only one who seems to be having trouble with a number of units bought at various times from various suppliers.

Either you're doing something systematically wrong, or you're incredibly unlucky. Don't buy any lottery tickets. ;-)

Or send me a couple of your DOA Pi's as I'm too tight to pay for one to use just as a toy, which is all it would be for me. I'm reasonably sure that my curiosity would persuade me to get at least one working.

I can't get me 'ed around how you'd enter that using RPN...

Avtually its morelike 'I put the same petrol amnd oil into my 5 fords but the key only starts one. Therefore fords are s*it'

As I haven't used RPN for about 20 years, nor can I.

On an HP21 it'd be: (set DEG/RAD switch to DEG)

I think... I could check it out on Monday when I'm at the office. (I re- populated my battery pack with a two-pack of NiMH batteries from Poundland...) Having lots of [(hp)] experience helped when I moved on to 8087 programming.

Not necessarily - he might just be a miserable old fart, whose faculties are failing him.

Don't you want to see if he can come up with any more ludicrous crap?

On a HP 41CV:

If not (already) in DEG mode: [XEQ][ALPHA] D E G [ALPHA]

Regards and hava a nice day Julius

Or some young fart with no more patience than brains...

...

Good find. That seems quite likely.

Maybe 4 of them are diesels.

And since they're s*it I'm not going to bother finding a mechanic or returning them to Ford for a refund - I'm just going to leave them in my yard to rust away.

If my experience with the Sinclair Scientific is anything to go by, what you do is carefully press the buttons in the sequence described in the manual, with little feedback as to whether the calculator is doing anything, then eventually get "Err" displaying iirc. You then repeat this process three or four times until getting fed up and putting the shoebox full of old calculators back in the cupboard in disgust :)

If this were a common problem, I would expect the fora to be awash with complaints though...

Which could mean, you have borderline knackered cards which basically don't work, but one pi is a little more tolerant than the others...

(remember most static damage does not (contrary to popular belief) result in immediate catastrophic failure, but often manifests as reduced life time, or unexpected operation)

Same as above...

Might be worth trying the "DoA" ones from a bench PSU
