Thanks for the info, Jazz.  I would also like to read that writeup.

I also have thirteen 02's and four 03's that have the 'A' revision of the CPU if they are of interest to anybody?

(and an 06 with a 'C' revision CPU - but I'm keeping that one!)

Hey DaRkO, what revision is the one in question, anyway?

08 Mate!

I have a stack more here which I'll be checking also and I'll post up results as I go.

Jazz, this one has gold link port contacts too.

The only 07 I have found has proportional serif text on the silk.

I plan on blogging about some of the subtle aesthetic differences from board to board. For example, 07 has square corners on the ground pour whereas my 08's have chamfered corners. My 07 has a larger CPU blob, but only by a mm or two. 'ONE' of my 08's has gold pins on the link port; the others all have silver.  This particular board also has a large "C" screened in the middle above the CPU which is not present in any other board. One 08 has a dark pine-green solder mask, and the others have a light green.

Then there are the great differences between the earlier revisions and the 07/08's.

Off to work. sad

Nope, only 07 and 08. I have a dozen 08s and have had a dozen more over the years, but have had only one 07 ever. Same board though, slightly differing silk screen.

Those blobs where a much cheaper way to make IC's back then. You could just print them on the pcb, and cover it with epoxy.

It was cheap, and harder for people to copy the technique. (Chinese knock-offs)

All of my DMGs are CPU 06 and I've never seen blobs like this in a PiL...Very cool though...

Not in Australia apparently, I have had quite a few PiL's but never seen this style of board, this particular one is out of a regular DMG.

Haha it's crazy, after all the consoles I've had, modified and taken apart, this was the first one I've seen like it.

Nothing amazing, just the same chips in COB (Chip On Board) instead of packages, so it's the die directly wired to the board and covered in epoxy, but still unusual smile
