Stilphen, Scott. "DP Interviews Paul Allen Newell". Digital Press. "When I left [Western Technologies], there was no "game" [Entombed], just the [maze] algorithm. Steve Sidley was hired when I left and inherited what became Entombed, with Tom Sloper as game designer. I have documentation of that in the form of framed games with plaques that WT had in the halls that were rescued when lots of stuff got thrown out (nobody could find the Scramble one). I quickly versed Steve in 6502 and the nature of the maze algorithm and took my leave." --Paul Allen Newell
