  performed a heavy editing cut on this article, referring to it as a cleanup. Had to revert it since it was a deletionist cut off of focused/main info. 

 * Pinout comparison: Pinout diagram shows the main differences between PC and NC. Flatting the diagram colors doesn't really make it more expressive. 
 * External links: There are worldwide only a few emulators manufacturers. It would be strange, talking about hw emulators, not to link to them. 
 * Floppy interfaces: You can't simply understand practical hw emulatiion if you don't understand the main floppy interfaces. 
    

 :* The point of Wikipedia is to present knowledge here. External links should be used sparingly for information which can be found elsewhere which cannot be included here for whatever reason. They are not to be used for general portal links. This goes doubly when you quite evidently control at least one of said links, and trebly when said link is to a page where you make money from selling the linked product. All of those links should be removed again. 
 :* The ""floppy interfaces"" comment is presumably due to the alteration of the heading ""FDC interface"" to ""interface"". There was no actual removal of information there. It most certainly did not warrant a flat revert under a ""vandalism"" summary. That one at least doesn't need to be reverted right now, although the article still needs completely rewritten and the headings will undoubtedly change again during that process. 
 :* The current table layout is completely unreadable. Quite aside from massive overuse of HTML (about 4kb of pointless markup all told), coloured headers would be far less useful than, say, adequate labelling of the data. For now, it's easy enough to cut down on the junk markup without actually altering the table layout, though again the whole thing will probably need completely rewritten. 
 :* Obviously the most galling thing here is an editor with an obvious conflict of interest reverting good-faith edits as vandalism, though the petty swipe at ""deletionists"" didn't help either. This obviously needs attention from an editor with good technical knowledge and good English to progress further at this time, though I'll try to reincorporate those changes which shouldn't ce controversial now that Blackvisionit has been warned.

 ::Edited version of the pinuot table was worse than the previous one. I agree when  says that it can be improved, but readability should prevail over compactness.    

 ::Floppy interfaces comment is about the removal of the Floppy interfaces external links. I've had to search internet for over a week to find them and believe it or not they are unique. Instead of removing it could be worth to turn them into a specialized article. Let's think about it.    

 :::Regarding the conflict of interest:  Yeah, you cannot really include your own personal website/blog.  If it is really, really relevant, you should ask another editor to review it and insert it for you.  In any case, your page is simply a redirect to http://embeddedsw.net/EMUFDD_Floppy_Hardware_Emulator_Home.html  so there is no purpose to using your page: just put the latter link in.  I agree wtih ChrisC that it would be nice (the perennial WP wish) if some technical expert in this field could improve the article.  I am troubled by the lack of citations (footnotes).  What is the source for the information in the body of the article?   Technical web sites can be okay, if they are the only choice.  Blackvisionit:  What sources were used for the text in the article?  and for the pin data table in the article?  Did that come from a book or web site? which one?    

 ::::The manufacturer comparison lists EMUFDD, PLR, HXC, QHSFD, FLEXIDRIVE, SWEROB, and DDR, but the references only link to EMUFDD.  That's biased.  There are few enough makers of FDD emulator hardware that all should be listed under External Links. Also, the manufacturer comparison has a bunch of orphan asterisks. Did somebody do a cut and past without including a footnote?
