curprev20:3220:32, 28 October 2019 Johnsiretttalkcontribs 9,593 bytes+524 A paragraph within this article appears to be a direct quotation from a 2013 work "The History of Visual Magic in Computers" by Jon Peddie; I have added this as a citation. I also believe that this work may contain a typo which was copied to Wikipedia. I can found no online references to the existence of an '82C441' chip, I believe Jon Peddie intended to write '82C451', which clearly existed and was contemporary to IBM VGA cards. Please revert this edit if you find evidence to the contrary.undoTag: Visual edit
