Different, Reviews, Rate the age of the equipment

My ways to determine the age of the equipment.

Rate the age of the equipment - Be reliable.

Especially on online auctions, I see a free approach in indicating the age of the equipment.
Ten years in electronics is a significant difference and a laptop with a hard disk should not come from the early 80's.

Knowing the device model symbol, we can find a description on the internet. You can assess the age of the equipment by reading the encoded date of manufacture or warranty. The codes on integrated circuits are the best seen. When the circuits are two and more it is even easier to find the production code.

For some people it will be obvious what to write next, but there is a group which is not aware of the ease of checking the age of electronics based on the production date code. There are different ways to encode the date of production.

I usually use a four-digit code applied to integrated circuits as can be seen on the attached photo of the portable Compaq board.
Two-digit year of production is recorded here 89 to 1989 and the last figures indicate 34 weeks of production year.
Together it was August 1989. In addition to the four-digit code, letters may appear as an additional manufacturer's code, meaning eg the time of day (day / night).

Here you will find additional ways to identify the date of production.
