"PVT" on iBook clamshell logic board?

[647156]

Meant to ask about this ages ago but never got around to it - I noticed this marking on my Indigo clamshell's logic board, normally I associate the "xVT" designations with prototypes but this is just a normal retail iBook - does anyone or everyone else's second-generation/FireWire iBook have "PVT" on the board underneath the memory slot?

The one shown at http://www.powerbookmedic.com/iBook-G3-Clamshell-366MHZ-Logic-Board-p-16252.html also has it.

I'm guessing if they don't all have it then it is the ones from early in the production run that do, its serial number starts UV039... which suggests it was produced a couple of weeks after they were released - I assume it's pretty insignificant, but was just curious

Iv noticed this too on PowerBook medics Lobo

interesting that yours has it too.

I suspect that indeed just an early production machine, some of them do have PVT marked on them somewhere, I have some systems with PVT on their lobos(Late 2006 MacBook2,1 IIRC being one), but its a sticker rather then a silk screen marking like yours, a True PVT (production verification test) machine will usually also have PVT marked out on the case somewhere along with "This thing is not FCC certified and may cause you to get abducted by aliens" etc etc

some intel macs also have fun stuff in the bootrom, like all MacPro3,1s have "Proto1" in their BootROM and and all iMac6,1s have "DVT" in their bootROM, I guess apple forgot to remove those values before releasing those Machines/ROMs
