С наступающим новым годом. Рпивет из Украины.

Hello from Ukraine. Happy New Year. Thanks for your channel. I always look with pleasure. I wish you good health.

Ah yes. The 1802 "Cosmac". I designed many a product using it. Back in the day, for a CMOS processor there was only this and the Intersil 6100 (emulating a 12 bit PDP-8) while other manufacturers kept saying "we will have our CMOS version 'next quarter''" And the "next quarter" turned out to be a couple of years I think. Rather unique architecture with any of the sixteen 16 bit registers assignable as the program counter or stack pointer. And no "call" or "return" instruction making you having to write your own if you wanted nested calls. And you could single step it and stop and start the clock if you wanted. In one product, where speed wasn't needed, we ran it from a 32,768 Hz watch crystal that was otherwise used for time keeping. The 1802 was an early processor for military operations in a militarized version.

Timo that is amazing HP built some really good test equipment in the day !

Thanks for sharing your story Timo!

I wonder how long these digital counters were continued at HP? The original spare-part module I have is mfg'd in 1965 so apparently there was quite steady demand, even though this counter must have been a very costly unit to purchase. Or maybe they just kept providing spares? There must be an issue of HP Journal covering these questions, I'll see if I can find it :D

@@MLX1401 Army maintained tube-run lab equipment very long time until 1980s. They were supposed to be nuclear and EMP-proof. And especially when dubious semi-soviet country like Finland could not get MIL-hardened stuff from Murica.

Cool !

$500 would be $4700 in today's money and $2500 is $23,500!

Online inflation calculator says $500 in 1957 is equivalent to $4795 today. Pricey bit of gear back when.

Yep, "portable" meant "probably won't take more than one person to move it" 😂

@Larry Butler Actually, I found something that did beat the "self-lighting" florescent tube (although at a transmitter site I worked at, we did that, too). We had many AN/FRT39 (Technical Materiel Corporation GPT-10K) 10 KW transmitters. If you let an interlock open, a shorting bar in the high voltage section dropped down on a huge filter capacitor. And if that final stage was under power, it made a heck of an explosive "craaaack" sound. We had some supremely obnoxious officer "inspecting" our facility and he was being guided down a pathway between the backs of two rows of these transmitters. So I pulled out one of the exciter drawers on one that was on, but not currently being used. It was pretty effective. At a cal lab I worked at, they had a good solution for humidity. They had a large air conditioning unit running 100% of the time, and then heating coils in front of it to regulate the room temperature as needed.

Some more numbers. BLS online calculator says $2500.00 in 1957 is equivalent to $24,728.47 in 2021. I knew a guy that worked for the railroad in the 1960's at $12/hr. (1965 @ $12/hr. × 2000 hrs. = $24,000/yr.; adj. for inflation 782.4% in 2021 @ $105.88/hr. x 2000 hrs. = $211,760.00/yr. with full benefits, a decent retirement and alcohol vending machines ;))) He paid $8,000 for a new 1500 sq. ft. home with full basement and 2 car garage that he was still living in until he passed. The housing market reflects the inflation rate far more accurately than wages after 1970 when Nixon destroyed the partial Bretton-Woods gold standard for Rockefeller oil (that's why O.P.E.C. happened and Carter's austerity measures). JFK saw it being planned. There was plenty of oil for refinery worker families while everyone else waited in rationing que lines. My friend's home cost 1/3 of one year's wages plus he got all the extra benefits that the corporations dumped during the Reagan administration. College tuition for pre-med school was $3,000 a semester in 1982, but wages and jobs and credit scores screwed up the wage rate confusion about the increased speed of the dollar decline from puppet 1970 Nixon. Wages fell way behind for entry level labor and then in the 1980's for a lot more of blue collar labor after Reagan fired the picketing air traffic controllers. $8,000 in 1965 adj. 782.4% inflation is $70,589.97 in 2021. Do we see those kind of new home prices today? We absolutely do not for a new 1500 sq. ft. home with real lumber, good roofing, solid hinges, windows and doors anywhere even in the most rural stretches of America because the dollar has an on-purpose failing foreign capacitor with new wet currency generating shorting through most of the circuitry. See what I did there? Ha. 1957! When they built the best Chevy ever with standard interchangeable door hinges that flipped upside down for either side of the car, standard round headlights and room to walk thru past the back seat. There have been major improvements since then and a lot of tradeoffs like better passenger crash survival and air conditioning, more quiet and less stinky to plastic doors that crack in the winter from a kick, no real bumpers and the idiot engineer that thought taking door bumpers off and reducing parking space size was good for car door finishes. But, VW's in 1969 with carburated 4 cylinder engines did 85 m.p.h. and made 35 m.p.g. without all the electronic gadgetry. Today's average cars make less than 30 m.p.g. and usually have an electronic malfunction that puts them in the weeds. Thought you'd like to see my honest perspective over surviving those days in actual dollar equivalents of one of the phases in the fall of the American rust belt that led to today.

:-) same here.

I always laugh when he says that.

Yes it is very sad to see what was once a quality company go down hill so far.

@@rjkee5157 Yes, back in the day we used to equip our labs with HP, Tek, B&K, R&S, etc kit, all "Engineering Driven" - where are most of them now?

@@pjaj43 Fortunately, Rohde & Schwarz (R&S) still exists.

@@heinzk023 As are Brüel & Kjær ( B&K ) but their range of equipment seems to be different from what I remember using in an acoustics lab back in the 1970s.

The philosophy lives on at Keysight Technologies. The same divisions, Santa Rosa (RF/uW), Loveland (DVMs, function generators, etc). and Colorado Springs (digital oscilloscopes and logic analyzers). Many of the same people. I just retired in 2021 after 42 years and many of the engineers there have been there since the 1970s.

Not to mention those early circuit boards are a thing or real beauty!

It depends on where those radios were made and price range. Radios made in Germany, France, USSR for example at least had a transformer and had no live chassis (especially when case had metal parts in contact with the chassis). And obviously cheap radios were made... cheap, compared to this quite expensive piece of test/lab equipment. More expensive radios were rather well designed too, just way less complex.

@@shadowflash705 The transformer less radios were known as ac/dc radio's. They could operate on 120 VAC or 120 VDC. so for a remote cabin with no VAC they would just line at 10 car batteries in series and still listen to the radio. One big disadvantage could be the hot chassis, or in any one of the tube filaments went out not radio! on some of those AC/DC radio was even the dial line was in the series with all the tubes. You could tell the freq counter in this was later in the 50's with all the miniature tubes.

It is certainly impressive looking at how far digital technology has taken us since one of these earlier digital devices.... Imagine an all-tube (valve) iPhone... probably come close to the size of a planet or at least a moon.

Glad you enjoyed it!

I was thinking exactly the same thing. Time for a Kill-a-Watt.

Probably 200 watts... Hmmm?

@@johnnytacokleinschmidt515 Could probably do a fairly accurate guesstimate from the heater draw plus a few ma for the HT supply .... assuming they're ECC83/12AX7) But easier to get a meter on it !

@@johnnytacokleinschmidt515 More than that...

Happy new year!

Happy new year!

Thanks for stopping by Marc. Happy New year!

Happy New Year Rocco!

In 50s and earlier planned obsolescence wasn't a thing at all. I have a fan that was made two years after WW2 - it works perfectly and only things that were done with it on my memory - it was oiled twice, first time, second - in 2016, also old plug was replaced with modern one. Even a power cable is still perfectly fine after all those years. Almost 75 years of running 2-5 months a year, often 24/7. In very late 60s they started to cut the corners but it wasn't true planned obsolescence yet, they were just making stuff cheaper to make more money. And things were still very reliable.

It's only "planned obsolescence" since better things come out. I mean, you can still buy and use flip phones, but few do.

The February 1968 Popular Electronics issue was probably the first one where they had such an article, and PC board layout, for making a decade counter board with 10 incandescent lamps. It used Motorola RTL integrated circuits. I'm quite familiar with it because a friend and I etched a number of boards based on the design (while stationed in the Navy on Midway Island) but modified it to drive Nixie tubes which we were able to scrounge. We made 12 boards. He made a counter from his six boards. And I added a little circuitry to do the necessary resetting of decades to make a 6 digit clock. Back then, a Texas Instruments TTL decade counter was about $10 and a decoder driver for Nixies was about $15. A lot of money. We couldn't afford that. That's why we jumped on that article with its less expensive Motorola IC's.

Yes, that was quite a series.

It is only a small lateral move from being steampunk.

Happy new year!

I agree! I restore old broadcast 2" video tape machines, and after perish, no one will have an interest in these machines all will be lost and left for the history books im afraid. How sad. Even in museums, they are usually static displays and not fully functional like it was back in the day, when they were working 24/7

You are very welcome!

You can build up a 30V "pack" using smaller cells (3x9V cells, or 2 stacks of 5 x 3V Lithium coin batteries).

Thanks! You too!

"USA were decades ahead of all the other countries on earth" That statement isn't true.... UK has been at the forefront of technology with many inventions. As an example, we had the first digital programmable computer using vacuum tubes. It was called Colossus. It's existence was kept secret for many years.

Wasn't 1957 the year that Sputnik from the Soviet Union went into orbit well ahead of the USA?

We still are, just not in domestic manufacturing.

Thanks for sharing your story Dave!

Thanks! Happy New Year!

It's HP. All their equipment was well built.

@@rubusroo68 - sadly HP now days does not do the great job like they did at the past !!! All Best in New Year !!!

Thanks Ryan, same to you!

Happy new year!

Isnt it obvious - Mr Carlson has possibly invented a Tardis. 😆

Space heater! You could probably cook dinner on it!
