This article seems to have been digitized with OCR. I've found several glitches: Smalltalk-8O, 'dis play', and other mistakes caused by OCR that should have been caught by a spelling check. Issues with quotes are apparent throughout the article: quotes ending with `“` instead of `”` (see the first paragraph) spaces between single and double quotes (`“ ‘` and `’ ”`) make lines starting with quotes look odd and leave a lines with just a double quote on it at the end of a paragraph (the second paragraph ends with a `”` on it's own line) I also found this quite interesting: > One innovative use for the network had nothing to do with people sending messages to one another; it involved communication solely between machines. Because the dynamic memory chips were so unreliable in those days, the Alto also ran a memory check when it wasn’t doing anything else. Its response to finding a bad chip was remarkable: “It would send a message telling which Alto was bad, which slot had the bad board, and which row and column had the bad chips,” Thornburg said. “The reason I found out about this was that one day the repairman showed up and said, ‘Any time you’re ready to power down, I need to fix your Alto,’ and I didn’t even know anything was wrong.”
