Whatever happened to Sinclairs idea of intelligent fault-tolerant wafers
that simply blew the links to duff dies and worked as entire assemblies
of chips ?

Probably yields improved and the amount crammed into a tiny section of
the wafer made it unnecessary - his original intention was for the 512KB
RAM pack for the QL to be wafer scale, but we have moved so far past
that that it is perhaps unnecessary.
