Ian was right - Sinclair was definitely developing a wafer chip - or
whatever the name was.
The thought was also that being so large, it could incorporate parallel
logic. The idea behind this was that if there were faulty logic paths
in production, then others could take over.
........ or maybe other logic paths could be created to bypass faulty
sections.
Even with current low cost silicon, there is still a high rejection
rate.
That, as was said , cannot be afforded with a bigger chip.
