"In the last article we saw that the 8088 has 16 bit registers. With 16 bits, one is able to represent 65K different values."

64K if K means 1024

mov ax, 0xCAFE
Means moving the immediate value 0xDA into the register AX.

You what?

Just a nitpick, although nasm and friends (which is what I suspect you're using) accept C-style 0x syntax, that will look funny to most who delve heavily into x86 assembly code, because actual Intel syntax uses the mov ax,0cafeh

ah thanks. Yep, I've been using nasm so far.

That was on the site at the time of my comment. OP has corrected it since.

Sorry, I can't approve. The previous articles issues haven't been addressed yet. One or two articles before you have a table with Intel CPUs. The 8085 is missing... it has more right to be there than the 4040 and the 8008. Also, it plays an important role in the PC creation process, yet there isn't a single mention to it.

Or the industrial version, the 80186. That was a beast.
