A look under the cover. The floppy drive is at bottom right; to the left is the 68040 CPU under its heat sink, and above it is the hard drive. The power supply and fan are on the left, and the 4 SIMM slots are just to the right of the power supply. This machine is somewhat rare because it's a standard (non-Turbo) NeXTstation that takes 72-pin SIMMs. Most non-Turbo machines used the older 30-pin SIMMs. Essentially, this one is a Turbo motherboard with the slower (25 MHz instead of 33 MHz) processor.   (8/14)
