-
-      <para>The DEC3000 series were among the first Alpha machines
-      ever produced. They are based on an I/O bus called the
-      TurboChannel (TC) bus. These machines are built like tanks
-      (watch your back).</para>
-
-      <para>DEC3000 can be subdivided in DEC3000/500-class and
-      DEC3000/300-class.  The DEC3000/500-class is the early high-end
-      workstation/server Alpha family.  Servers use serial consoles,
-      workstations have graphics tubes.  DEC3000/300-class is the
-      lower-cost workstation class.</para>
-
-      <para>DEC3000/500-class are quite fast (considering their age)
-      thanks to the good memory design. DEC3000/300 is crippled
-      compared to DEC3000/500 because of its much narrower memory
-      bus.</para>
-
-      <para>They are called <quote>Birds</quote> because their
-      internal DEC code names were bird names:</para>

-
-      <para>Currently DEC3000 machines can only be used diskless on
-      &os;. The reason for this is that the SCSI drivers needed
-      for the TC SCSI adapters were not brought into CAM that the
-      recent &os; versions use. TC option cards for single (PMAZ-A) or
-      dual fast SCSI (PMAZC-AA) are also available.  These cards currently
-      have no drivers on &os; either.</para>
-
-      <para>DEC3000/300 has 5 MBytes/sec SCSI on-board. This bus is
-      used for both internal and external devices. DEC3000/500 has 2
-      SCSI buses. One is for internal devices only, the other one is
-      for external devices only.</para>
-
-      <para>Floppy devices found in the DEC3000s are attached to the
-      SCSI bus (via a bridge card). This makes it possible to boot from them
-      using the same device names as ordinary SCSI hard-disks, for example:</para>
-      <screen><prompt>&gt;&gt;&gt;</prompt> <userinput>BOOT DKA300</userinput></screen>
-
-      <para>The 3000/300 series has a half-speed TurboChannel compared
-      to the other 3000 machines. Some TC expansion cards have
-      troubles with the half-speed bus. Caveat emptor.</para>
-
-      <para>The embedded ISDN interface is not supported on &os;.</para>
-
-      <para>DEC3000/300-class uses standard 36 bit, 72 pin Fast Page
-      Mode SIMMs.  EDO SIMMs, 32 or 33 bit SIMMs all will not work in
-      Pelicans.  For 32Mbyte SIMMs to work on the DEC3000/300-class
-      the presence detect bits/pins of the SIMM must correspond to
-      what the machine expects. If they don't, the SIMM is
-      <quote>seen</quote> as a 8 Mbyte SIMM. 8 Mbyte and 32 Mbyte
-      SIMMs can be mixed, as long as the pairs themselves are
-      identical.</para>
-
-      <para>When you find yourself in need of fixing 32Mbyte SIMMs
-      that lack correct presence bits the following info might be of
-      use:</para>
-
-      <para>There are four presence detection bits on PS/2 SIMMs.  Two
-      of the bits indicate the access time.  The other two indicate
-      the memory size.</para>
-
-      <para>At one end of the SIMM there are two rows of four solder
-      pads.  One row is connected to Vss (GND) and the other is
-      connected to pins 67 (PRD1), 68 (PRD2), 69 (PRD3), 70
-      (PRD4).</para>
-
-      <para>If you bridge a pair of pads with a small resistor or a
-      drop of solder you ground that particular bit.</para>

-      <para>DEC3000/500-class can use 2, 4, 8, 16 and 32 Mbyte 100pin
-      SIMMs.  Note that the maximum memory size varies from system to
-      system, desktop machines have sacrificed box size for less
-      memory SIMM sockets.  Given enough sockets and enough SIMMs you
-      can get to 512 Mbytes maximum.  This is one of the main
-      differences between floor standing and desktop machines, the
-      latter have far less SIMM sockets.</para>

-      yourself. Programming information for TC boards is hard to
