Does anyone have plans to interface the link port to a microwire bus with as few parts as possible? The prob with microwire is that it has an input and an output line instead of a tristate bidirectional line. There are 8 m-bit chips for microwire, (1 megabyte, cool) so if you just have one of those connected to the calc, your golden. I was thinking maybe using diodes to make the input and output line into a tri-state line?
