 Posted: Mon Feb 09, 2009 7:25 pm Post subject: Pentium engravings to iPP or not iPP |
 |
|
seeing i have a few multiples of ceramic pentiums i noticied that some of the same sSpec had the old engraved markings on the base while others had the new iPP marking.
Looking at the dates it didnt necessarily work out old and new, so i was wondering if there was anything else to determine which should have the old and which to have the new marking
i did have a third pair to show, but the print rubbed off one on the first wipe  looks like other fake, but thats another story

I also collect different cap versions of 486's and Pentium's. iPP is much more common than iXX IMHO.

| This engraved marking is a good protection against relabeling. |

Yes, I guessed that is why they did it. They seem to be part of the ceramic 'moulding' rather than engraved. |
