I took this core apart out if curiosity having dismissed it as junk because it had a production serial number and didn't boot. When I took it apart, I found some dvt 5 stickers in it and decided to investigate further. it does boot with normal 210 parts but is extremely buggy. It often freezes and won't shut down properly. Either it was a junk test or it just doesn't quite community community production firmware correctly. Hard to say because Sony either destroyed mold old ip after aibo was discontinued or they still have it but the public will never see it because that is just how Sony is, even with ancient ip.
