I've been mulling over a way to do this for a few days now, and I hope someone can enlighten me, even if it's to tell me I have it all wrong. This is regarding Powerbooks with limited internal memory capability, specifically the 2400 that I will be acquiring soon. Now, I've heard of Compactflash cards being used as volumes for virtual memory, but also that this is pretty slow, especially reading the data may be slower than a hard drive. Knowing that the bus itself is capable of so much more, I've looked all over for different kinds of memory to plug into those precious slots (basically processor direct right?), but it's all forms of (slow, costly) static RAM that's meant to preserve contents in the absence of power, whish is to my mind a completely superfluous feature for a volume to be mounted strictly for VM. One example of memory expansion beyond 80MB would seem to be the installation of one of those Travelstars HDs with the 8MB buffer. Designate that as a VM drive, and a significant chunk of the virutal memory will often be sitting on actual RAM, ready to be accessed across the fast and wide PCI architecture with read access times that would barely allow for CF to begin to putter about its NAND gates.
So, what about it? What's the trick? An external Firewire HD with a huge buffer? External DRAM that format's itself at bootup to look like an ATA-accessible formatted volume? I did see a few references to PCMCIA DRAM, but it all looked proprietary and/or hopelessly out of date. Thanks, Ed -- PowerBooks is sponsored by <http://lowendmac.com/> and...
