CLisp design and implementation details?

["Dwight Hughes" <dwighth@intellinet.com>]

Is there any documentation available on the internal design of CLisp?
I am not referring to info like the implementation notes that are part
of the binary release - what I want is a general overview of the
design and why it was done that way (type of gc, memory organization,
stacks, tagging, 32bit versus 64bit mode operation, ...).

Any assistance appreciated.
