HP65 Update



#11

Well, it finally arrived. It is in great cosmetic condition, albeit filthy and and in need of a good cleaning. Unfortunately there seem to be some issues with the ON-OFF and PRGM-RUN slider switches--the display cuts out at times, does wonky things, and the calc freezes occasionally, so entering and running a simple program eludes me at present. However, if handled gingerly, she stays alert long enough for me to test the display and all of the key functions, and they seem intact. I am suspecting some internal connection has become soiled or loose. The card reader works, but sluggishly, and I think I detect the ominous streaking so a repair is wise. I am not too fussed about being able to restore the unit to full working condition--my HP41CV had similar issues with a wonky display and our friend Randy resurrected that like some sort of HP Lazarus. So far, I think the LED itself is alive and well and that there is no dreaded mono-key failure, one of the few things that Randy can't fix.

I think the seller did a cursory test of thing, was able to to some basic math, and chalked it up as "working" (in fairness to him he never said "working perfectly"). I have asked him to consider sharing the cost of any repairs over and above Randy's flat rate (which I was expecting to pay even before knowing of the extra issues) if they are required. I must admit I am a bit disappointed, but I think the thing can be coaxed into a full and useful life. To my great joy, the manual and QRG are nearly new, the Standard Pac and Surveying Pac are almost complete (only one blank card missing, all program cards present), and even the old battery has a bit of juice left (though I know it will croak soon). The plastic grey case is just retro-cool--sort of a proto-laptop thing, if you will.

I should say that after an HP41 IR module just paid for I must put a moratorium on my buying for a bit. I went a little crazy over the holidays and I don't seem as good at getting the really good deals as some folks are. But I have developed a very gratifying collection so far, and since I don't spend my money on booze, women, gambling, or fast cars, I am quite satisfied with myself.

Just thought I would share the saga with those who understand :)

Les, the slider switches are simple spring-metal contact type switches, very prone to dirt or fatigue based failure (after about 30 years), but also very easy to service and restore to full function. Poor or dirty contacts on the switches would probably account for the display and freezing issues, so it's probably a very easy fix. The fact that the card reader works, at least electrically, and the overall condition, tells me this unit can probably be restored to excellent cosmetic and working condition.

Steve,that is good news. I am not about to attempt a repair myself or even to open it to take a look--I don't want to destroy the back label, for example.

I was able to get far enough to load a mag card and to switch the calc into PRGM mode long enough (before the display cut out) to discern that some program steps that match the manual's were indeed loaded. Can't seem to execute an entire program--power and display cut out and program memory gets erased unpredictably with playing with the upper part of the calc (slider switches and label keys).

I think I mentioned that, if I am lucky, the non-program function of the top row keys seems intact, but only if I put adequate pressure between the the two slider switches to maintain uninterrupted current, and even that doesn't always work.

I have written Randy and already have the packing materials all set to go. I am still waiting for the HP67, which I know needs a card reader, and along with the 97 I got last month the three of them will make the journey to PA for the Master's touch.

Thanks for your optimism! I need it--I was pretty discouraged at first to get it out of the box and to encounter this.

Hello!

Congratulations for your latest arrival, as Steve already said, it should be easy to bring back to near-perfect condition. I'm still lacking an hp-65 (and also an hp-70 I'm afraid) to complete my classic series, after which I will probably have to put a stop to systematic collections due to prohibitive prices...

Well, I don't spend money on any of the items on your list either, but a family, a mortgage and a horse force me to stick with the "really good deals" which become more and more rare.

For Christmas I went a little crazy too and bought me a very nice hp-80 (perfect deal according to my eBay bidding policy "model-number = amount-to-bid-in-Euros-or-dollars") and a Curta Type 1 (average deal and still in the mail - can't wait for it to arrive).
For the rest of the year, it's going to be flea-market instead of eBay for calculators.

Greetings, Max

NB: And please dispose of your old NiCd cells properly - these things are really bad for the environment and should have been forbidden worldwide long time ago!

So should I infer that you paid EUR/USD 1.00 for the Curta? ;-)

Or 16 EUR/USD for an HP-16C? I like your algorithm though. I think I'll try model #+N from now on.


#17

Except for the ones that I bought new then they are at regular prices. For the used ones that I got I stay fairly close to the formula I think.
I overpaid a 10C for $3.
I got a great deal with the 97 at $0
I got 6 41CX's blanknut like new condition at the right price of $5 each.
I underpaid a 41CV for $.50.
I got a 9825B for $5 but I don't know if the right price for it is $9825 or $25 but in either case a good deal.


#18

All I can say is WOW! I must acquire more patience!

#19

I have totally missed this formula, alas. I am getting a bit more patient and less inclined to be hosed, but I have no aptitude or patience to get the real bargains.

I just figured that between the actual cost, shipping, duty, and anticipated cost of Randy's repair work, my recent 65, 67, and 97 acquistions together will have cost me about $1250US ($1500CDN), and maybe a little more if the chowderheads at Canada Customs charge me to reimport my own stuff back into the country after it is repaired. (That doesn't include $50 for extra battery packs since they also get used in my HP45 and HP41 printer.)

Do I think its worth it? You bet. When I anticipate spreading those costs over years of enjoyment, this is still a pretty cheap hobby, even in the hands of the "bargain-hunting impaired" like myself.

Maybe, one day, I will stumble across a great bargain a la Antiques Roadshow, and the karma of it all will balance out. When I consider this, it is hard for me to be envious.

Don't feel bad Les, just consider the original MSRP, and adjust for inflation. See? Instant bargain!


#21

That's right--about $800 each for the 65 and 97 and $400 for the 67 in 1970s money....

That strangely makes me feel better.

Now that would have been nice and I would still have some money left for hp classics ...

No, with Curtas the bidding formula is a little bit more complicated and goes rather like this:

maxbid = -0,008475 * SerialNumber + 1008 - (30 AND !Handbook) - (50 AND !Boxed) - (200 AND !Working) - (X AND Damaged) - (100 AND BadlyWorn) - (Y AND SellerHasNegativeORnoFeedback)

But as a matter of fact, I got 3 of my 4 HP41s on eBay using my "HP bidding rule", 2 HP28s, one HP18, at least two HP21s, my HP46 (yes, really!), the HP55, a 10B ... and an HP19C also, but only if you read the "C" as a "0" ...

Unfortunately, this nice little forumla works less and less well, because people with seemingly unlimited supply of money have started to ruin the prices :-(

I wasn't able to find such a deal on an HP-81. Had to pay about 8n.

But at least I got a much better deal than that on an HP 9100A.

Still looking for the 9805A, 9821A, 9830A, 9831A, and various peripherals. But definitely not willing to pay n dollars each.

#24

Like death and taxes, the card reader failed at about 930 pm tonight, EST. Had to fish out the stuck card with tweezers. Telltale goop all over the thing.

When yer time is up yer time is up!
