- NeXTcube Turbo (68040-33MHz), NeXTstation Turbo
- (68040-33MHz), NeXTstation Color Turbo
- (68040-33MHz), newer NeXTstations (68040-25MHz), and
- newer NeXTstation Color (68040-25MHz):
-
- These systems have only 4 SIMM slots, but they can take
- double-sided SIMMs. SIMMs must be installed in groups of
- two in these machines.
-
- Use 72-pin 4, 8, 16, or 32 MB SIMMs with 100 ns minimum
- access time. For maximum performance use 70 ns SIMMs.
