Drawing Trader Sheets back in the day.
I can not begin to imagine how these complex circuits were drawn accurately. I realise they would have had circuits from the manufactures, but TS had their own layout / style that makes them easy to follow and would need re-drawing. Would there have been a team? each doing their own set? How would they correct a mistake? Then I presume it would all have to be made in reverse for printing. Anyone know of someone involved making the TS.
John.
