From: "Chuck Guzis":
It seems to me that using MRAM or FRAM would keep the
spirit of the
idea alive, being magnetic memory and all. 'course, it doesn't need
to be refreshed after a read...
Agreed, though iti is intrinsic in all the transistor and TTL PDP-8
designs to always write after read. So you'd have to either let the
writes through, or suppress them within the replacement memory
subsystem itself.
