Proof that 40 letmy often criticize Apple for the fact that the current generation of computers and laptops, the company virtually eliminate the self-upgrade.

But, whether we like it or not, it has always been.

We got a publication of the American programmer and inventor Andy Herzfeld. It dates back to 1981. Just this year, he served as senior software architect OS for the Macintosh computer. By the way, his autograph can be found inside the case of the Macintosh 128K.

And in those early years it became clear the ideology of Apple. Closed and not allowing access to the internal components the user with a complete absence of the possibility of independent behavior.

Jobs: No additional ports and slots

This computer started a total limit of upgrade.

The ability to self-extend the functionality of the first Macintosh by installing additional cards in the appropriate slots was considered one of the most controversial moments in the development of the computer.

Apple co-founder Steve Wozniak believed that users should have the opportunity to expand hardware. So the Apple II received from seven built-in slots for peripheral cards, and the computer architecture was designed to fit a wide range of applications.

Specialist in computer interfaces, JEF Raskin, and, in fact, the initiator of the Macintosh project, on the contrary was convinced that slots and ports only hinder the development of personal computers, pushing away potential buyers.

Ruskin was convinced that the expansion of the hardware makes it difficult for third-party developers, since it is more difficult to develop FOR, given the consistency of the underlying hardware.

The availability of additional slots on the motherboard of the Macintosh is something of the red book.

So Apple decided to abandon hardware scaling, avoiding the increase in the cost of their computers, but depriving users any way affect the performance and functionality of their Mac.

Position of Steve jobs in this issue was vanishing towards Ruskin. According to the founder of Apple computer Apple must be enclosed in a tightly sealed enclosure, and the ordinary user there is nothing to do.

The position of the jobs was not shared by the software developer for Mac Burell Smith and his assistant Brian Howard.

Barell understand that while Apple will promote Macintosh and attempts to increase the sale of the computer, he will have time to become obsolete. Besides, we were the completeness of the software. Simply put, there was a risk that the Macintosh will hit the market already outdated computer.

Full set of “closed” from the Macintosh user.

That is why Burell believed that the Macintosh needs to obtain maximum flexibility and the possibility of an upgrade.

He suggested that the Board of Directors to install Macintosh in a single slot, through which one could access the processor bus. Steve jobs has spoken out against, but Barella just wouldn’t stop.

Then Barell decided to apply the idea of the introduction port under the pretext of saving money on production. The port called the diagnostic, and its use, the assurance Smith, could greatly facilitate the testing device in the production phase.

The inscription on the back side of the case as it suggests: “do Not go, kill!”

And although Smith was at first well received, a few weeks later, engineers started to pin programmer “diagnostic port”.

The secret victory of the barrell

Thousands of enthusiasts thanks to Burrell, then calmly carried out an upgrade of the memory of their Macintsoh 128K. And save hundreds of dollars.

During the release of the Mac with 128 KB of RAM Burrell is especially worried about the fact that this model will soon become too weak for the buyer. He knew that to expand memory enough to bring only a few extra lines on the Board.

With their help, any person who has at least a little friendly with a soldering iron can easily conduct your own upgrade computer for mere pennies.

But Steve jobs was strongly opposed to buyers have access to Macintosh hardware. Instead, he was presented expensive model Mac with 512 KB of RAM. But Burrell was a very stubborn person.

Realizing that the slots for additional RAM needs to be, he just left it on the motherboard. Steve jobs, this one does not warned, and the customers later said thank you for the opportunity to conduct independent memory expansion.

Apple is not changing. Hi, T2
This chip soon will be hated by all external services involved in the repair of Apple technology.

Surprisingly, on the background of this story, the events that unfolded nearly 40 years ago, Apple has released Mac mini with upgradable RAM.

However, the company has a backup ACE in the hole. iMac Pro, MacBook Pro and Mac mini 2018 — all these computers come with a chip T2. And his presence itself provides full control from Apple over any self-upgrade.

T2 works so that any repairs in the informal service center, providing for the replacement of components would result in a total failure of computer to boot. To bring it back to life will only be possible by testing on specialized equipment. And is it only in authorized service.

The ideology of Apple has changed over the years. Like 40 years ago computers this company was created exclusively for a user who don’t need to know what and how to succeed inside the system unit or housing.
