Motherboard (Was: The Burroughs B5900 and E-Mode

OED researchers found published use of "motherboard" in 1971, but no idea how long it had been used as a term before that written reference. So, B5500 could be before "motherboard" was a term. Although, I remember a mention of it in conversation in 1967. Much like the common usage of "bug" LONG before Grace Hopper used the common term in a log, "inventing the term". OTOH, renaming "Altair Bus" to "S100" happened over a few months. Some used "motherboard" to refer to a simple set of multiple connectors, such as S100, whereas some will only use it if it has significant circuitry on it, not just termination. -- Grumpy Ol' Fred cisin at xenosoft.com
