Pcb Design On The Bbc Pc1512/1640 Computers

EE 45 PCB DESIGN ON THE BBC Xier■elb PC1512/1640 COMPUTERS Many constructors shy away from building even the simplest circuit when a printed-circuit board, or the artwork for it, is not available, forgetting that there are now affordable computer programs that enable track layouts to be designed and edited on screen with various options available. The output of these programs is transferred to a printer or a plotter to obtain the required artwork that, in turn, can be used to produce a transparent film. What was long considered the exclusive domain of professional engineering departments has now come within the reach of thousands of owners of home computers: computer assisted design (CAD) of printed circuit boards is now available at relatively low cost for a num- ber of the most popular computers. This article introduces two PCB design pack- ages: • PCB for the BBC-B, B+ or Master with discdrive (Archimedes version also available); • PC-B for the Amstrad PC1512 and PC1640. ...
