BTW there were two 8600/9600 motherboard variants. The first would report itself as the x500 series in OS X, and the second, the "Mach 5" version, would (at least should) report itself as an x600 series. The Mach 5 variant replaced the traditional 604/604e CPU card with an enhanced version that had 1 MB of inline L2 cache built in that operated at the processor's full bus speed of 100 MHz instead of the x500 series' soldered 512k L2 cache speed of 50 Mhz (system bus speed).

The 9600 in this thread (the one the linked pictures depict) is the Mach 5 variant. You can tell because the lower right quadrant has four large chips and four smaller ROM chips just above the upper right of those first four chips. This motherboard, due to the lack of soldered cache, was much more tolerant of G3/G4 upgrade cards, since the bus speed wasn't hampered or limited by the pitiful cache Apple used on the 9500 series motherboards.

The downside to these motherboards is that regular 604/604e cards did not work in them, but none were released with the speed of the Mach 5 variants anyway so that isn't much of a downside. However, for optimal stability with G3/G4 upgrade cards, 2k EDO DIMMs were required as the regular 2k/4k FPM DIMMs' tolerances weren't tight enough to support the faster cards with much reliability.

Both motherboards retained the ROM SIMM slot.

Received the ZIF card and ZIF today from mc68k. No idea how he was able to get it shipped/delivered so quickly. Clearly sellers on eBay ought to take note of his techniques. I still don’t have the 9600 in my hands. Hoping to acquire it sometime this month.

I just got a recently retired quad-nostril G4 that I don't know what to do with, so I stood it up in the middle of my home office and plan to frequently trip over it when I'm stumbling to the kitchen to get a glass of water at night, so that eventually I'll have to do something with it.

If anyone in my part of Oregon wants a quad-nostril 867MHz G4, let me know...

I should have kept my 9600/350. I recall that there was some fsb speed issue?

Hmm do you remember what FSB issues? The biggest issue I had was just with the raw 50MHz speed. Even with a 1GHz G3 and a bunch of other goodies, it would struggle to play higher res non-HD videos of the time. The G3s with their slightly higher 66Mhz FSBs and memory were noticeably faster

Did you ever upgrade yours? Who did you sell it to?

Wow this thread brings back memories! I had a 8600/250 that I later upgraded with a XLR8 carrier G3 zif (400 mhz). I'm positive I got Leopard running on that machine using XpostFacto and the newer MachSpeed Control 3.5 software offered by Daystar. I bought that software in May of 2010. I still have that XLR8 Card as well as an old Newer Technology Max Power G-3 L2 card pulled from a StarMax from the 'Clone Wars' era. I wonder if those cards have any value at all?

I always had terrible luck with upgrade cards in any of the 8xxx or 9xxx series machines. Not a single one that I ever used ran really reliably after upgrading, even with the bus speed turned down.

There was some memory bandwidth issue I think that showed lower performance than I got with my Power Tower Pro. I can't remember exactly but I think that it might be archived at Mike's site? I think that it went to eBay in 1999.
