Sonnet PPC PCI Card

Apparently the card's CPU needs some kind of activation sequence. In (wild) theory, this could also work in an Amiga:
- PCI video/sound cards are no problem if slot-to-slot DMA works.
- Acessing the legacy adress space would be pretty tricky: you'd need to set up the MMU to trap the access, generate the appropriate 68k code and let that run instead. :lol: This could actually work even though it'd probably be pretty slow.

BTW: anyone got 5V DIMMs he's willing to part with ??

I've got a PowerMac 9500 here, souped up with a G4/1000(!), but only 64 MB inside.
I've tried using old Compaq server DIMMs, but they seem to be 3V and OS X keeps crashing on installation. OS9 seems to work OK, but the NIC refuses to receive data - very strange actually.
The best deal I could find was on macsales.com - $19 for 128 MB. Not bad, but shipping to Germany is >=$29...

Yes, 168 pin, FPM or EDO.
5V have the middle notch slightly to the left (towards the other notch), the notch on 3.3V ones is centered between the contacts.

As DRAMs are rather tolerant towards higher voltage, I've 'modified' the Compaq DIMMs with a cutter, which somewhat works. The original sticks have 74FCT162244 buffers while the 3Vs are 163244 - couldn't find any exact specs, but that's probably the only thing 3V on them since the RAMs themselves are 5V types...
