Recently, I came across something interesting: an iBook prototype. Well, more precisely, a PVT (Production Verification Test) motherboard inside a defective iBook: the power connector was dead.
In iBooks, PVT (Production Verification Test) motherboards are quite common. Even at PowerBookMedic, the illustrative board is of this type.
You can still see a PVT inscription, a confidential IBM CPU, and the typical iBook ports. There’s a fairly large connector at the end of the board whose purpose I don’t know, and traces for memory. A thread on MacRumors discusses these, as they could potentially allow for additional RAM. An original iBook has 32 MB on the board + one SO-DIMM slot; the later ones (like this) have 64 MB internally. But with four internal slots, it’s theoretically possible to upgrade to 512 MB (and thus 1 GB in total).
Unfortunately, the hard drive contained nothing interesting.
