I've been digging through some spares in boxes I had and happened upon a G4 processor that I bought about a decade ago when I was rebuilding a Sawtooth, as it happens a GE Dual processor card landed in my lap shortly after I bought this one so I never actually used it.
I was 99% sure I remembered it being a 400Mhz unit and was idly contemplating what to do with it so I looked for some markings to confirm, this is where it got puzzling....
Every single G4 I have ever seen in the flesh, (which is probably only about 30-40) has been clearly marked up on the die, and easy to identify. This one not so much.
I've attached pics although I couldn't get the markings on the die visible with my phone camera. The markings are smaller than normal, so small I can't read them without a magnifying glass and don't follow the normal format I'm used to, it reads:
YHA07008TB
LYLY9JX
0 06-12
The die is NOT square like most of the lower clocked 7400s I've encountered, it's decidedly rectangular but doesn't look as small as the 7410 dies I've seen.
The rest of the daughter card is an entirely normal OEM Apple part with the c2000 markings, and the bar code markings indicate a 400Mhz (INDONESIA P10 400).
So what is it? Is it just another Motorola 7400 variant without the normal markings? Hoping some of the more learned PowerPC folks might know!
I don't really want to go and pull apart my only compatible Sawtooth to plug this in at the moment to investigate further but will if needs be!
