In fact, you can run Virtual on an SE/30 RIGHT NOW, and have up to 14 MB. If you have money to burn, you can fill the beast up with 4MB SIMMs, and use Maxima to have up to 14MB as user RAM, and the rest as a RAM disk which will survive anything short of a power-down. Above that, 32-bit mode is only useful to people who have huge amounts of fast disk space to swap, or have more money than they know what to with, in which case they buy large amounts of RAM. R.
