I own a 9600, how can you find out if you have a Kansas or Tsunami mother board.
The easiest way, assuming that the machine works, is to boot the machine, look in Apple System Profiler (ASP) under "Production Information", "ROM Revision". A Kansas machine will have ROM version $77D.34F5. A pre-Kansas 9600 will have ROM revision $77D.34F2. A 9500, Genesis, PowerTower Pro, or S900 will have $77D.28F2.
The ROMs are physically four chips approximately 1.1" X .5" with forty-four pins--twenty-two down each long side of the chip. But you can identify the machine without opening the case by using ASP.
The ROM revisions break down as follows:
$77D.28F1 (chip markings: 341S0106 through 341S0109) -- Some 7200s. Possibly some early PowerCurves.
$77D.28F2 (chip markings: 341S0168 through 341S0171)-- All the other 7200s, 7500, 7600, 8500, 9500, Umax J700, Umax S900, PCC PowerCurve, PCC PowerCenter, PCC PowerTower, PCC PowerCenter Pro, PCC PowerWave, PCC PowerTower Pro, Daystar Genesis
$77D.34F2 (chip markings: 341S0280 through 341S0283) -- 7300, 8600 pre-Kansas, 9600 pre-Kansas
$77D.34F5 (chip markings: 341S0380 through 341S0383) -- 8600 Revised (Kansas), 9600 Revised (Kansas)
And for good measure:
$77D.40F5 (F1, F2? memory is hazy) -- Beige G3, revision A $77D.45F1 -- Beige G3, Revision B $77D.45F2 -- Beige G3, Revision C, All-In-One
The Beige G3 uses a two chip ROM module instead of having four ROM chips soldered down. I am hazy on the chip markings but IIRC, the Revision C has 341S0494 and 341S0495. The revision A has something considerably less than that like ...0405 and ...0404 and I've never seen a production Revision B. The only one ('B') I saw was built on four AMD Flash chips so it didn't have Apple part markings on the chips.
OWC has a page that tries to help one identify Beige G3 ROMs by the circuit board markings, which was nice of them, but has points of failure. They could have made it very simple, if they'd just gone by the chip markings. There's no telling which circuit board a chip will be soldered to, but if Apple marks a ROM chip with a specific part number, it comes with a consistent ROM code on board.
