Hewlett Packard 5082-7000 Display

Post02 Mar 2013, 01:05

Hamilton presented six prototype watches to the public in 1969. The module has been produced by Electro Data and is known as the 44-chip module today. The following picture by D. Klein shows how the module looked like. I don´t know if modules survived but I doubt it.

Electro Data ordered six custom made displays for one module, based on HPs first LED display, the 5082-7000. Last autumn I got a few of these from the UK. I made a small test unit and took some pictures. OK, these are not great but you get an impression how they look like.

1969 Wow that early! Interesting to see that they used a double line of dot segments to create a curvier number.

What size are the digits, are they small enough to build into a watch?

I think it would be great if you could make or retro fit a watch using these digits - could it be done or would you want to preserve them?

It is said that the HP 5082-7000 is the overall first LED display produced in series. The digits are roughly 7x5mm (0,28"x0,2") in size. The display holder is 27x15.

Here´re five reasons why you cannot use them in a watch:

1) Their total size
2) They dissipate too much heat.
3) The total current flow is more than 100mA / display
4) They are super rare and not that easy to obtain
5) New ones in original packaging have been sold for more than 800 USD / piece, used ones sell for about 150-300USD.

Moreover they are running on 5 volts. Of course that could be done in a watch, but it doesn´t make things easier.

Neat-O. Love the shape of the digits. It shows how much more could have been done than the standard 7 segment displays.

Yeah, the extra row of dots make a big difference......they look awesome :mega:
Size was certainly a big issue for Hamilton. The Electrodata module had specially produced packages. The bottom digits for seconds are oriented sideways, and the hours digit is cut in half............all in an attempt to reduce overall size. Pretty sure I read on OldPulsars that Electrodata produced there own PCBs and sent them to HP for addition of the diodes and chip.

So with 5.5 of these in a watch it'd draw 550mA when displaying :eek: :eek: ?
Hamilton must've been very confident of rapid improvements to announce the watch with these displays. I think this was the module that kept running out of batteries on the Johnny Carson show.

I too have some 5082-7000's :-D They were initially produced in Feb 1969, and were the worlds first "Solid State Numeric Indicators". They used an array of individual but very inefficient LED emitters. Depending on brightness and number being displayed, they can consume up to 150ma !! That would be nearer 5ma these days.

I would have thought the original 1970 P1 prototypes had reduced brightness to preserve the batteries for their initial launch and the Carson show. And I'm not surprised the prototypes only lasted 20 minutes between battery swaps !

Also, bear in mind that the original ED circuit, and the final P1, all used multiplexed displays at 64hz (I think..) IE, only one digit is on at any one time, and its persistence of vision that makes them all look on at once. In other words the maximum current is still only going to be the most used by any one digit and not 500ma - that would kill the button cells in seconds, and probably get a tad hot.


Another interesting point about the 1970 P1 prototypes was that they didn't show hours+mins+seconds all at once. It was either 4 digits for Hours+mins, or 2 digits for seconds if the button was held down. If you look at the ultra rare P1 users manual that some owners still have, it shows two photos of the 1972 P1 using a 6 digit 25 chip E/D module with 4 digits on, and the 2nd photo shows just the seconds working in the lower part of the display, below the hours/mins .. which of course vanished when the initial P1's were all recalled and the modules upgraded in late 1972 to use the P2 circuitry.

Ah yes..........multiplexing :oops:
And yes your right, the seconds did display separately. I'm pretty sure Jonny Carson exhibited this feature on the show.

Thanks for clearing that up.

Does anyone know if there is an online link or youtube video of the 1970 Johnny Carson show with the P1 ??? If there is, I cant find it !!

Many years ago I bought a DVD with many Pulsar related video clips on it, but as far as I can recall the very grainy JC clip was so bad you couldn't actually see if the watch was on/off etc.

Any help appreciated !!

I couldn't really see the digits either, but I'm sure Johnny talks about it as he's pressing the buttons.

Actually, I just watched it and you can see the seconds counting........more noticeable right at the end. They're much bigger than you expect. He does talk about it too.
Here's a screen grab:

You can just make out a 0 or a 9 above his thumb nail..........looks more convincing in the video.
Obviously I've got the video...........it's about 400M though, so not sure how I'd get it to you.

Thanks for the photos and information SASM, those vintage displays are wild, especially when you see the aesthetically pleasing
approach taken to make the numbers look more curved and easily recognizeable.

I'll try to upload the video from a DVD format to youtube.
The last time I offered the disc on eBay was nearly 10 years ago....now you have online video streaming so I hope it works on YT.
I guess that is called rapid evolution :mega:

Nice display Hanno ;-)
I didn't realize the size of these until I seen this :eek:

I tried to buy the ED module as I regard it as THE Holy Grail. I just cannot imagine a more significant artefact that represents the very origins of the entire digital watch era of time keeping.

Back in 2008 I put down a deposit on the module when it came up on ebay, in an attempt to secure it, but for various reasons we never concluded the sale and the seller returned the deposit.





I've added a scan below taken from the 4 page Hamilton brochure dating from May 1970. It shows the 2nd Electrodata module shrunk to fit within a watch case, and uses the trimmed 5082-7000 "numerical indicators" as HP called them. If you look closely at the watch photo it appears to be an actual working watch module with the 5082s crammed in, and working. You can just about make out the un-illuminated LED dots of the seconds display area below the upper 4 digits. I've not able to find a better photo of one of these prototype watches.

Cool Diginut, Thanks for posting this!
I never saw this auction before, just found some pictures from it I guess :scratch:
That really stinks that you never received what you paid for :x

I remember that auction some 5-6 years back or less.
Mr. B is from the UK so why don't you pay him a visit? Maybe he got sick or had other issues.

I remember this auction; it went for some silly money like 8000 pounds (about US$12000). Interesting, but not worth P1 money. BTW, if you're cropping stuff, don't leave any part of the name; "Phil" can only be Phil Bowler, who is still active on the "other" Forum. His website is still up, so I presume he is still with us. My understanding is that he also has one of the Hamilton prototypes; the name of the ex-ED employee who had these items was never revealed.

Sorry Abe, couldn't resist.....aren't those still 7 segment displays? :grin1: Yeah, yeah, you meant sticks vs. dots. Shame there isn't some better nomenclature .... most dot displays are 7-segments from a logic standpoint.
