Where to get them?
Well MacOS 9 and prior had some of those fonts eg Chicago and Geneva, but most of the Macs I have are too new. Ahh but I do have an old iBook, and the original disks, which is old enough to be still shipping with Classic, according to everymac, and the disks say they shipped with OS9 and OSX 10.4.
