Just a note that I hope will be helpful.

The 8500 and the Umax S900 have exactly the same firmware.    They 
both use the ROM Revision $77D.28F2.  In fact, the 7500, 8500, 9500, 
7600, PTP, PowerWave, S900, J700 and Daystar Genesis all use this 
identical version of the firmware.   Also, many of the 7200 use it as 
well, although some 7200s have $77D.28F1.  Oh, and the PCC 
PowerCurve, PowerCenter, PowerTower and PowerCenter Pro also use the 
$77D.28F2 firmware.

The four ROM chips are marked 341S0168 through 341S0171 for 
$77D.28F2.   They are marked 341S0106 through 341S0109 for $77D.28F1.

The 7300, and original 8600 and 9600 have updated firmware.   The 
revision number is $77D.34F2 and the four ROM chips are marked 
341S0280 through 341S0283.  I don't know if this update made any 
changes to Open Firmware.

The 8600 Enhanced and 9600 Enhanced (Kansas machines) have a still 
newer revision, $77D.34F5 and the four ROMs in these machines are 
marked 341S0380 through 341S0383.  Again, I don't know if this update 
includes changes to Open Firmware, but this is the version of hte ROM 
which allows proper operation with Speculative Processing enabled 
when using G3 and G4 processors under the MacOS.

Incidentally, the ROMs/firmware from the 8600/9600 Enhanced works in 
the earlier machines including the 7200 and fixes the Speculative 
Processing issue.
