Are there any PCI upgrades that the PTP 225 can NOT take ??
In my experience, no. I've put tons of different cards in my PTP over the last couple years, including 2 or 3 64-bit SCSI cards, and the only ones that don't work are non-Mac cards.
I notice it has 8 DIMM slots, and my 9600 and Daystar Genesis MP 800+ both have 12 DIMM slots. How diffeent is the logic board in these 8-DIMM clones???
Probably the only downside is the 1GB limit, rather than 1.5GB the 9500/9600/Genesis have. The logic board in most of the PTP systems have all the same chipsets and specs as the 9500/9600 Tsunami design, though it does look different. The only *functional* differences are 1) the cache is next to the processor slot and is removable, rather than soldered on. 2) the board is slightly smaller and fits the extended-ATX format(the mounting holes are even in the correct places for those adventurous enough to do a case change); the power supply is also standard ATX, so if the current one dies, you can grab another from the local PC store or something. :)
There is a rare, late-model revision motherboard that was redesigned for the never-released PTP G3 systems. I have found it functions the same overall, except Sonnet's 700MHz/800MHz upgrades don't work. XLR8 fixed this issue in their Carrier cards years ago, so they work fine, as do most of the other upgrades. It was usually present only in some PTP-250s.
If you're curious, look at the bottom front corner near the speaker...there is a model number printed there. If it happens to be PCC 5000-0141-01, then you have this rare model. If it says anything else, you have the "standard" design.
It appears that the internal bus runs at only 45 MHz. Is this a problem ??
The PTP motherboards are usually capable of running up to 60MHz, sometimes faster; all of them should be able to run at least 50MHz. Some of the older 604 CPU cards used lower bus speeds for various reasons, mostly techy bits involving the CPU multipliers and such.
