The TI people were selling their chip as a simple four operation
calculator. Here is what the Sinclair people did with it:


An interesting project that Sir Clive was involved in was the wafer
scale integration effort by Ivor Catt.


The goal was to eventually do what the Cerebras people are now doing
(with lots of positive press), but their first products attempted to
replace hard disks with battery-backed wafer scale SRAMs. The many-core
processors would come later, but as HD densities took off (after only
having grown slowly from the mid 1970s to mid 1980s) the investors
pulled out.
