I've thought about an array of reed switches for

be just enough magentic field to hold the reed closed once closed
but not enough to cause it to close by itself. The coils would
then be used to open and close by applying a counter or aiding
field to the reed/magnet. The magents would be arrange with alternating
directions such that there was no accumulating of the magentic
field across the array of the reed RAM. ROM can be done with
and array of diodes and switches.
Why not just use a very large core memory instead and sence the
output with a very sensitive relay?
I'd keep the ALU simple since most times, it
doesn't need to
do arithmatic. A single bit ALU with a few serial storage
shift registers would be sufficient for most math operations.
You hope, homebrew CPU's have a way of growing on you. :)
Also so does memory. :)
