80-BUS PORT MAP

Owing to lack of supply of information from two companies (see Editorial) there seems little point taking up pages detailing information that may be in error. However, there is a definite need for some published information on who is using what ports, so the following page gives brief details of the port arrangements recommended by each manufacturer for their own boards. If you know of any additional boards that should be listed, please supply the information ASAP. In the next issue we hope to publish this information in much greater detail.
