Basically, title. Got a couple of G3s a few months ago. One of them in great shape, 512 MB RAM, PCMCIA 802.11n card (although it only works under OS X) and a rare Wegener Media G4 at 550 MHz. The daughter card looks just like a stock one but apparently the folks over at Wegener grafted on a G4 and added 1 MB L2 cache. And I have two other G3/400s, one is in great shape (just needs new hinges), and the other is just for parts.
So the maxed-out one is where I'm having problems -
1) It doesn't boot reliably. Sure, it chimes 100% of the time, either with its new battery or plugged in but very rarely POSTs/Happy Mac (or activates the display) without having to reset the PMU (via back panel).
2) Appears to be more stable under OS 10.3.9 than 9.2.2. I reinstalled 9.2.2 and may downgrade to see if that matters but I get a cache failure error dialog every time I boot into OS 9.
3) I need a recommendation on replacing the 2.5" HD with a CF, preferably an SSD. I can't seem to find a good IDE-to-SATA adapter that fits with the SSD inside the Pismo.
Elaborating on #2, under 10.3.9 System Information, under Diagnostics, the POST reports: Failed. I downloaded a couple of cache utilities - one from Sonnet and another from PowerLogix - to see if the cache was properly configured (clock multiplier). According to the utility, the 1 MB L2 runs at a 2:5 ratio to system clock, which, on a 550 MHz G4, would be 220 MHz.
But that's apparently not correct: according to https://web.archive.org/web/20071230072602/http://www.wegenermedia.com:80/pg4550.htm, the L2 runs at 250 MHz, which is something like 5:11, not 2:5.
But, making any change - even to manually enable it - causes a freeze. But I'm only assuming this PowerLogic cache utility is compatible with whatever is on this Wegener-modded daughter card.
So I summon the "Oracles of Pismo" to share your thoughts on any or all of the above. Thanks in advance.
