I came across an A3000 with the serial number "00003252" which if read normally would indicate it's a very very early A3000. Is there anything special about this machine?
Not particularly, I don't believe. It would be a production model and should have all the same specifics as any others of that motherboard revision. You may need a slightly different set of kickstart ROMs for it (ROM Tower). I forget exactly what the differences are, but I'm sure a bit of googling can still help out, if you're needing to upgrade it to 3.1 ROMs.
