The product is an external RAM-disk, connected to any Mac via the printer serial port. It then has a serial port out its back to which you can connect your printer; you aren't out a port. It comes in .5, 1, 1.5, and 2 Meg versions. It also comes with a software driver/configurer that allows you to define it as up to four different volumes. Anything you don't assign to a volume may be used as a printer buffer. Since it is powered by its own wall-mount transformer/supply, it retains its memory even when the Mac is off, thus making it much more friendly than the RAMdisk. Power consumption is low (10 Watts) so you can leave it on at all times. Optional battery back-up is available, too. The idea seems sound, especially as we are (presumably) all familiar with the speed of the RAMdisk. The literature points out that many people who purchase hard disks don't really need the vast storage; they're after SPEED. This is a cheaper (?) alternative, and is also much faster and quieter and more reliable (no moving parts). They admit to being slower than a RAMdisk by 15%, but then they're hampered by the serial port. They claim to be faster than Hyperdrive overall, with Hyperdrive's transfer rate 2 times faster but QuickDrive having zero access time. They claim to have a modular enough design that when larger 1 Meg RAM chips are available, they can be installed through pluggable modules and yield drives with 4x the above sizes. Prices, you ask? 0.5 Meg $499 1.0 Meg $649 1.5 Meg $799 2.0 Meg $949 Battery Backup module $149 Expansion module (adds 0.5 Meg to existing QuickDrive) $169 each, or $150 each if within 30 days of original purchase. No, I don't have one yet. This item was first mentioned in this group about a year ago; I just now got literature on it. I suspect that is because they just now have gone into production. I am seriously considering purchasing one of these instead of the Mac+ upgrade. I will still get the new ROMs and dual-sided floppy drive, though. The address and phone: MacVentures P.O.
