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.
