The last MP3 patent

The last MP3 patent

Medieval Europeans believed that the divine right of sovereignty transferred instantly from one monarch to the next upon the death of the previous one. This led to a saying, first used in 1422 in France, that translates to “The king is dead. Long live the king!” And in that same spirit, when the last patent related to the MP3 file format expired April 16, 2017, a few people said MP3 is dead, long live Mp3. And some skipped the part about MP3 living long, and just declared it dead.

Cyrix 486SLC CPU: Introduced April 13,1992

Cyrix 486SLC CPU: Introduced April 13,1992

On April 13,  1992, Cyrix debuted its 486SLC CPU. Cyrix didn’t have its own fabrication plants so they relied on other chipmakers, such as SGS Thomson and Texas Instruments, to manufacture the chips. Part of the agreement allowed TI to make its own derivatives of the chips, and share the advances back to Cyrix. The 486SLC was really more a 386SX/486SX hybrid than a true Intel 486 clone. It plugged into a 386SX socket and had the 486 instruction set and 1K of L1 cache. But clock for clock the Intel 486 was faster in a fair fight, and having just a 16-bit external bus kept it from being a fair fight.

Atari ST introduced April 8, 1985

Atari ST introduced April 8, 1985

It is hard for me to be objective about the Atari ST, because I was a dyed in the wool Amiga fanboy in the early ’90s. But the Atari ST was released April 8, 1985 and quickly sold 50,000 units. For a while, it looked like the future belonged to the Motorola 68000-based computers and the ST was going to be a big part of that.

Then again, since you probably are not reading this on an Atari ST, there is an argument that the ST was a failure. So it could be that I am grading on a curve. I expected the machine to be a nothing burger, and it ended up selling 2.1 million units at a time when 2.1 million units shipped still was a pretty impressive number.

Hayes compatible modem: What it means

Hayes compatible modem: What it means

A lot of software advertises itself as working with a Hayes modem or Hayes compatible modem. What does that mean? And what’s Hayes? It’s a de facto standard named after a defunct maker of modems. Let’s talk about why Hayes was important. It was so important, you can even still buy a USB Hayes compatible modem for legacy applications today.

Hayes introduced a command set that started with the letters AT, for ATtention. Other makers adopted this command set and cloned the Hayes modem to various degrees, leading to the terminology of a Hayes compatible modem.
