32 Updated the document to match the most recent changes to the CPU. Specifically,
these include the re-instatement of the full SUB command with immediate offset,
and ... others I cannot remember.

The new document also describes what conditions create pipeline stalls,
together with how many cycles each stall condition will create.

24 Lots more changes to the spec. It's still not done, but it is more complete
than before.

23 Oops -- left some portions of the RTC Clock spec in with the ZIP CPU spec.
These were quickly removed.

21 This update adds an incomplete version of the specification for the chip.
I ned to come back to this and do a lot more writing, but it is a start.

set.

8 Fixed the rotate left instruction to work in the zasm parser, and to be
properly referenced in the simulator. The instruction set documentation was
also adjusted to reflect what the CPU actually does.

7 Here's the iset.html file that was at one time in the gfx directory, but
which could not be moved due to a bad gateway error ... (Grrr).

project is at.
