Re:
A number of early small computers were
non-binary. One that comes
to mind is the IBM 1620 which was a decimal variable word lenght
machine. The 1620 was in production about 40 years ago and was
mainly marketed as a business machine. One of the interesting
features of this machine was that it did all its arthmetic by
table lookup.
Was that the CADET? (Can't Add, Doesn't Even Try)
I believe it was also known by that name.
