Similar techniques were possible on the PDP11, for example Coincidental to this conversation, I'm currently reading "The Apollo Guidance Computer: Architecture and Operation" by _Framk O'Brien_. (ISBN 978-1-4419-0876-6) Very interesting to see what you can do with a 15 bit architecture when sufficiently motivated. --lyndon
