Am amazed that you can find a computer with an OS where a verion this ancient will even work for you...
Seems Windows 10 will run it.
It's running my old 5.5 as well as my old Claris Homepage 3.0 and also my Server 5.
Just fooling around with it and only need to run some internal web pages etc. Contacts.fp5 etc.
Spent enough money on FMPro 5 and really only want the sample pages that came with 3.0
