Where can I find timing diagrams for the TINI Board?

There are no timing diagrams for the TINI Board as a whole, but there are diagrams for the CPU chip. Most of the external signals on the TINI board, for example the address, data, and chip select, are taken directly off of the CPU. All timing diagrams for the CPU can be found in the DS80C390 data sheet: http://www.dalsemi.com/datasheets/pdfs/80c390.pdf
