- <title>DEC3000 family (the <quote>Bird</quote> machines)</title>
-
- <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>

- <para>There is no X-Windows version available for the TC

- <para>Birds can be obtained from surplus sales etc. As they are
- not PCI based they are no longer actively maintained. TC

- find. Birds are recommended only if a. you can get them cheap
- and b. if you prepared to work on the code to support them
