I'm not sure, but the HP35 might even have preceded the Sinclair
calculator.
As with all "FIRST"s, an entry can be saved by redefining the field.
Sinclair's was probably the first one costing 5 pounds or less.
He still owes me the circuit board for his Black Watch. He shipped the
things without the PCB, just an empty case and battery holder.
Apparently, this was done for a number of people.
Anyone have a completed, working Black Watch? Or was this a case of
Clive blowing smoke?
