The BASE switch can be set for address in the range of 000-3F8 so it should not be
hard to find a free address area f or you CIO-DI##. Once again, if you are not using
IBM prototyping cards or s ome other board which occupies these addresses, then
300-31F HEX are free to use.
Addresses not specifically listed, such as 390-39F, are not reserved and may be
available. Check your computer for other boards which may use I/O addresses.
