Default Re: Drawing Trader Sheets back in the day.

Same experience as Cobaltblue, except designers had to draw their own schematics on D-sized frosted mylar sheets. Most people used pencil for easy correction, a few od us used Rotring pens (still got my pens) Stencils weren't provided, A few people bought their own, but most used rulers with freehand for everything else.

Mechanical designers got draughting tables with protractor mounted rule sets. Electronics people taped their blank mylar to big mylar sheets with a permanent grid on them. These diagrams were used throughout development and for PCB layout, test and manufacture.

A separate department drew fresh, prettier diagrams for manuals, but these weren't used in manufacture.

THe R&D diagrams went onto microfiche aperture cards for archive.
