0^2 = 1

Uh...zero raised to any non-zero power is zero. On the other hand, 2^0 = 1 .

I'd have to say after reading your most recent post you are in need of a remedial math course. Frankly, I'm not sure why you are here. You have completely ignored the advice and help that has been offered ...

So i have been reading many books since the last time I logged in and burning the midnight oil staying up late to trying and work this out. i turned over to the " an introduction to microcomputers volume 0"
which has a section about binary, and binary numbering system. , Now i have to stress maths ...

So memory cell 1 has 210. memory cell 2 has 4. so why times 4 x 256 --- ? is it because 4 is half of the 8 bits :shugs: , and 256 is becauseeee 0-255 can hold in a memory cell.?

so is the higher memory cell (2) is that because its physically higher in the number chain?
Suppose you put your 16 ...

now my theory is it whatever half adds up to the most out of decimal value , is that the high order byte too? or am i barking up the wrong tree.?
Suppose you have the number 1234 sitting in memory. A memory cell can only hold 0-255 , so the number is stored in two pieces. In the case of 1234 , the ...

There was another twist when 16-bit processors got into the mix (see middle-endian or The NUXI problem ), but you probably don't need to dig that deeply to gain a working understanding.
I have to mildly admonish you not to add to his confusion with the NUXI problem. It's not applicable to a 65(C ...

so little-endian flips the bits backwards so there high bits are on the left... opposed to the right
No; bit order within a byte is still normal, but when you have the two bytes of an address, the low byte comes first, and then the high byte. There's an explanation of why this helps performance ...

so i have taken on board the recommendations , but some one them e reads are mainly for the apple from what i can make out. ,

I'm gravitating toward the commodore / vic / c64 etc. i have again hit a learning wall again so i bought another book! this time 6502 machine language , for beginners it ...

hi all

so i haven't made many updates regarding the book i bought recently id hoped it would unfog the 6502 of things for me, and ultimately learn machine language which is my goal and further my machine language learning etc!. , the book i posted some pictures of was becoming very very complicated ...

so... one of the books i have ordered has arrived , the other one is coming from the states which isn't here yet.

so the book that did arrive is "an introduction to microcomputers volume 1 basic concepts"....

So i had all knowledge guns blazing!!
i found afew mistakes in the ...

so i have been on the hunt for further books , i found the book that was recommended to me by @BigEd


i later found another book Teach Yourself Assembler (Teach Yourself Visually)

i really want to learn assembly but it seems very very confusing to me. fingers crossed i get there in the end.

Looks like that was written later, as a prequel. So not an integral part of the original work. Whether it works well as a beginner's introduction, I don't know. Certainly between 1975 and 1977 there was quite a shift in popularity and motivation for getting involved in microcomputers. So it could ...

Welcome.

A book I read decades ago that seemed quite good is Adam Osborne's " An Introduction to Microcomputers, Volume 1, Basic Concepts ." I have the 2nd Edition on paper, ©Nov 1980, ISBN 0-931988-34-9. It's out of print, but entering the underlined part above into eBay's search bar just now ...

Since there are a number of grease monkeys (or gear heads) here, I’m wondering what kind of processors are in engines nowadays. My knowledge is dated, but at one time CPU32 (MC68332, 68376) were used extensively as engine controllers and CAN bus is a common vehicle network. Automotive electronics ...

wow thanks all. i didn't except such a response , but happy :P

so i'll try and answer some of the questions , and it'll give you an insight of what I would like to learn why i have led my self down this path... , so s i mentioned i am a mechanic based in the UK , so i see mainly euro spec ...
