Since I've been on this forum the only acronym that completely flummoxed me was "MOT".
.. . . but I don't think that this is what the person who mentioned it was intending.

 

"Pyro" I was introduced to it in my early training.

MOT

I always took it as Ministry of Transport?

 

IPA isopropyl alcohol or India Pale Ale?

Intermediate Power Amplifier

 

I always took it as Ministry of Transport?

The government department has become the "Department for Transport" or DFT (or DaFT as it appears in Private Eye), but the MOT acronym lives on in the name of the annual roadworthiness test.

These acronyms and synonyms are just a fraction of the terminology used in electronics. The field is constantly evolving, and new technologies and terms emerge regularly, so staying up-to-date is essential for professionals and enthusiasts in the industry.

How many of those were around 40 ~ 50 years ago? It's a changing field.

Many were around back then, but many were not even concepts. But in 1973 we already had computers and a/d as well as D/A converters Also DIPs and PROMs. No SMDs as we know them, but there were some interesting schemes for automated assembly. The biggest difference then was that a fair amount of consumer electronics was considered worth repairing, and so there were repair shops that actually could repair things.

 

uF = MFD = micro-farad

Hz = CPS = cycles per second

The military gets carried away with this.
I worked on a MUTES ( Multiple Threat Emitter System) and a TRAINS (Threat Reaction Analysis Indicator System). How they come up with this stuff is beyond me.

I remember in the 60's CD meant Civil Defense, then Certificate of Deposit, Change Directory, Compact Disk...

 

Not too many are familiar with Pyrotanex cable or even ever worked with it.
Tubular Copper with conductors embedded in a insulating fireproof mineral '
Used in fire proof required situations, alarms, sprinklers etc

In the Navy they use similar type. It had steel braid on the outside and was filled with the mineral insulation like you said. Would periodically open a panel and the insulation had oozed making a mess in the box.

PyroTanex was/is imbedded in hard magnesium oxide material.

 

Working with it is a skill that is dying out.
Before long there will be demonstrations of it at country fairs along with thatching and basket-weaving.

 

That PyroTanex is one of very few electricl cables that will survive a serious fire in a compartment on a ship.

 

Anyone remember NTSC? AKA Never The Same Color Twice

 

Anyone remember NTSC? AKA Never The Same Color Twice

Never Twice the Same Colour (as told to me)

And Picture At Last ?

And PCMCIA

Anyone remember NTSC? AKA Never The Same Color Twice

Please consider, though, that adding color to a monochrome signal that remained workable, compatible with both, and doing it with vacuum tubes, was an incredible achievement.
Consider that digital TV benefits only the sellers and the broadcasters, and in one motion created a huge amount of E-Waste, as it is totally incompatible. In that one change they made every TV produced since 1950 obsolete. And for what benefit?? The quality of the programming is still down in the sewer, for the most part.

 

And PCMCIA
(People Cannot Memorise Computer Industry Acronyms)

Somewhere I have a real PCMCIA 1MB card with battery backup (that is, not non-volatile). I got it from the PCMCIA at Comdex in Las Vegas in 1990, it was a prototype and the only thing that (currently) worked in my shiny new PCMCIA slot.

So, why was the expansion of PCMCIA so hard to remember? Because it was a terrible choice for the purpose. It means “Personal Computer Memory Card Industry Association”. Why would the call the hardware that?

It also very rapidly came into use for anything but memory cards.

 

Certainly, "Y", and it is interesting how some creations are widely used for other than the intended purpose. the two that seem most used are USB, now utilized as a power plug, and POE (Power Over Ethernet) now being used for computer controlled lighting installations because it does not require the high-priced electrical workers. ( just wait until hackers discover how to switch off all the lights.)

 

I have to mention LASER (Light Amplification by Stimulated Emission of Radiation) because it's not an amplifier, it's an oscillator, so it should be a LOSER.

 

Look up erbium doped fibers, they are a true laser in every sense of the acronym.
