I forget where I found this (some forum dedicated to asm), but someone had stated that this was (is?) the best place to look at for learning ASM. It (as far as I have found) has the HTML files and the source code in seperate .zip folders, but no PDF verion (I tried making one, but gave up and just printed the website... one tutorial at a time). It uses the MASM assembler (it's mentioned within the tutorial, but I thought I'd say it first. I'm nice like that),
Someone (on this exact board I believe, the lounge that is) also posted a link to a site that offers free ebooks which has a section with a few (ten) tutorials. I don't know if any are any good, but you could check it out if you so choose:
I laughed a little bit when I went back to the lounge and found the topic I mentioned about free ebooks. I never would have remembered it was you who made that post.
