Great find - especially given the price. I have two G4 MDDs, one of which is flaky as shit, but the other is - as bibilit states - great as an intermediary between my 2012 MBP running Yosemite and all of my other networked classic Macs (IIx, LC III, LC 475, etc.). It makes transferring files between a 'modern' machine and a legacy one very easy (once the OS, AppleShare and OpenTransport are all installed on the older Macs, of course).
