How Do You Identify Logic board revisions for MDD FW800?

Question

I have a logicboard, the CPU board, and the heatsink for a PowerMac G4 MDD FW800 DP 1.25 that I want to sell, but I can't figure out what Revision it is (A, B, C) or if it is 133MHz or 167MHz. I do not have the computer (bought for parts) they came from anymore but I have my own MDD FW800 DP1.25 I could consult. Logic boards, I'm discovfering, don't make for easy reading--can anyone assist or point me to a "Logic Boards 101" text?

Hi-
The following should help to ID the logic board.
For the FW800 1 ghz board, the part is identified by looking at the serial # ON THE BOARD.
Look for one of the following code combinations in the
last 4 digits of the serial # : NME,P2X,P3E,P3G,P3U,P7P,P8E,
PFD,PFF,PFG,PFT
This would be the 133mhz model.
For FW800 multi processor boards, the part is identified by looking at the serial # ON THE BOARD.
Look for one of the following code combinations in the
last 4 digits of the serial # : NMF,P2Y,P3F,P3H,P3V,P7Q,P8F,
PFE,PFH,PFJ,PFU
This would be the 167mhz model.
For the MDD 167mhz, rev A, look for one of the following code combinations in the
last 4 digits of the serial # MXJ,ND0,ND9,NE2,NE8,NEV,NEX,NFA,NFG,
NG1,NKT,NNR, NNS,NNW,NRC,NWK,P8S,PG2,PG3,PG4,PG5,PG6,PGI
For the MDD 133mhz, rev B, look for one of the following code combinations in the
last 4 digits of the serial # : NF9,NG1,NNR,NRC,PG7
For the MDD 167mhz, rev. C, to determine which 167 MHz logic board is installed in the computer, check the AirPort Card connector at the edge of the board.
If there is a 2-pin fan connector on both sides of the AirPort Card
connector, it is rev.C. Otherwise use rev. A.
Look for one of the following code combinations in the
last 4 digits of the serial # :MXJ,ND0,ND9,NE2,NE8,NEV,NEX,
NFA,NFG,NG1,NKT,NNR,NNS,NNW,NRC,NWK,P8S,PG2,PG3,
PG4,PG5,PG6,PGI
