and the 8501 CPU's RDY signal also not available on the expansion port.
That is not exactly true. The CPU's RDY input pin is connected to TED's BA output which is also connected to the Expansion Port. The problem is that you should be able to read and drive this signal at the same time to achieve external DMA control in a system compatible way.
