Subject: I2. What type of memory may be installed in a NeXT?

  NeXT Computer (68030/68040), NeXTcube, NeXTstation:

  Cubes have 16 SIMM slots, Stations have 8 SIMM slots.
  SIMMs must be installed in groups of 4 in these machines.

  Use low-profile Mac II-style (30 pin) 1 or 4 MB SIMMs with
  100 ns or faster access time.  The low-profile vertically
  mounted 4 MB SIMMs are easier to install in the NeXTcube
  than the horizontally mounted 4 MB SIMMs because of the
  small height clearance above the SIMM slots.  It is
  possible to install the horizontally  mounted 4 MB SIMMs,
  but you will be required to slide the CPU board and the
  drive/power-supply tower in simultaneously.

  Parity (9-bit) SIMMs can be used in both 68030 and 68040
  NeXT machines, but should not be mixed with non-parity
  SIMMs. Only 68040 boards with ROM levels of 2.2 (v63) and
  higher can use the parity memory to detect parity errors.

  NeXTstation Color and NeXTdimension boards:

  These systems have 8 SIMM slots. SIMMs must be installed
  in groups of two in the NeXTstation Color, and groups of
  four on the NeXTdimension board.

  Use IBM PS/2 and Mac IIFX style (72 pin) 1 or 4 MB SIMMs with
  80 ns or faster access time.  The SIMMs are organized
  256kx32 or 1Mx32 for non-parity systems, and 256kx36 and
  1Mx36 for parity.

  NeXTstation Turbo and NeXTstation Color Turbo:

  These systems have only 4 SIMM slots, but they can take
  double-density SIMMs.  SIMMs must be installed in groups
  of two in these machines.

  Use IBM PS/2 and Mac-IIFX style (72 pin) 4 or 8 MB SIMMs with
  70 ns or faster access time.

  3rd party Prices:

  Given how dynamic the prices are in the memory market we
  can not provide an accurate compilation of suppliers and
  prices.  However you can take a look to see if there is a
  compilation of SIMM prices on sonata.cc.purdue.edu in the
  pub/next/FAQ directory.  If someone wants to volunteer
  to maintain such a compilation let us know at
  next-faq@media.mit.edu
