Xenarbor was further involved in promoting MyChess by David Kittinger, which running on a [|Cromemco Z-2] with Z80 processor won a match from Xenarbor 4 at an event of the [|Santa Clara] Chess Club in 1979. || toc =Etymology= The program's name combines [|Greek] and [|Latin] roots to mean "strange or alien tree", as explained by Miller to Boris Baczynskyj during ACM 1984.
