Hardware, Embedded Systems "The arithmetic-logic unit is a fundamental part of any computer, performing addition, subtraction, and logic operations, but how it works is a mystery to many people. I've reverse-engineered the ALU circuit from the 8085 microprocessor and explain how it works. The 8085's ALU is a surprisingly complex circuit that at first looks like a mysterious jumble of gates, but it can be understood if you don't mind diving into some Boolean logic."

Am I the only one that misses the old days when we had so many choices in both CPUs and even in X86? We had so many choices, Motorola and PPC and Intel, AMD, WinChip, Cyrix, so many choices! Remember what it was like when you could actually put a different CPU from a completely different company into a socket?

Now we only have 2 companies in X86 (three if you count Via but its nearly impossible to find) and while there are plenty of companies making ARM there just isn't the variation like we had.
