Basecamp for Mac loading very old TOPOGB map source

I have an elderly CD version of Topo GB - PC version with an 8 digit unlock code, how do I get the map loaded into a current version of Basecamp for Mac?

Thanks

Don't believe you can

An unlock code is 25 characters long. Your 8 digit code is a voucher code, used to register that map. I don't think that the registration server for those old maps is still active.
