@CanadaRAM: I think the SCSI cd burner might be the easiest route... the other stuff sounds like it could turn into a production.
I can possibly get my hands on a Lacie External SCSI SANYO 12X4X32 CD-R burner... is this what you're talking about? Can it be used without upgrading the OS?
All the other solutions posted are better than this one, but if you can't get the others to work, this is also an alternative. If you can get the old mac online then you'd be able to send the data through the net. The amount of data is probably so small that even a dial up connection would only take at most a day or two to upload.
>>It should have ethernet on it, although you might need the Cat-5 dongle to get it connected.
By 'dongle', do you mean the AAUI-15 to CAT5 adapter?
