Migrating 30 year old FileMaker data to something accessible is not for the weak.
@tantramar @harold So, I have the guest password … which works when I open the original FileMaker 2 file in FileMaker Pro 3 and 6 under Mac OS 9. However, I don’t have the admin password, which means I can’t remove the guest password.
Trying to access the same database with FileMaker Pro 11 or 12 under High Sierra causes those apps to crash when entering the password.
¯\_(ツ)_/¯
