The easiest way to get your files to a newer machine would be to install your drive in an external case and connect it to something like a G3 with SCSI and either burn it to a CD or put the files on a flash drive.

The next problem might be whether your new machine could read the files. There's a fair chance your currant software will be able to read the old format. If not then getting someone to translate them for you isn't a major deal.
