The chips were actually designed to be used in answering machines!
There are so many possibilities that this will bring that it's
mindboggling. =20
In terms of designing an actual 8 bit I/O port that you access
simultaneously with the expander, that will take some time, because I
haven't thought about how this can be done. I have a few ideas, and
I'm sure it's possible, however. I fear that a major problem may
occur, that it won't be easy to create an Input/Output port. You
could easily create an 8 bit output port, or an 8 bit input port, but
both at the same time will require a minimum of 3-5 more chips. For
now the usefullness of the synchronous design will be only for
expanding the memory to greater than 1 meg.
