I notice that even those guys that are building relay computers "cheat" and
use a single small solid-state chip for RAM. :-)
Hi
I've been thinking about how one could make a reasonable
memory, using small reed relays. If one puts a magnet close
to one end, it will cause the reed to close. Move it back
some and it will hold until the field is too weak.
If one set the magnet someplace in the middle of this
band, one could use the direction of current through the
coil to set and reset the contacts.
One could create an array of these for the memory. Placing
small magnets in opposite directions for adjacent bits would
keep from building too high a field buildup, in the array.
I was thinking that one could use small round magnets
glued to the end of a threaded rod. This could then be adjusted
to optimize the memory.
Now all I need is a pile of reed relays.
