Laptop Development Schedule
The XO laptop hardware development schedule has two more test unit builds (Beta Test 3 and Beta Test 4), before a final test build (C Test 1) on the final production line and mass production. The Beta Test 3 build scheduled for early May will be the first one providing the processor and memory capabilities of the production version.
Pre-production Test Systems (CTest-1, or C1)
This build is a very small number (200 or so) of laptops produced as a test of the manufacturing process on the main production line, and should happen in early fall. A C1 laptop is hopefully identical to a production unit in all aspects...
Beta Test 4 Systems (BTest-4, or B4)
This build, scheduled for the middle of the summer, is the final chance to fix hardware and mechanical problems that were detected in the Beta Test 3 build of the XO. Only a small number (200 or so) of these will be built for testing, as the injection molds for the plastic case have to be taken offline and duplicated to prepare for mass production (the Beta Test mold set will be retired after duplication).
No new features will be added to the laptop in this build. This build is planned merely to test solutions to problems detected in the BTest-3 laptops.
Beta Test 3 Systems (BTest-3, or B3)
This build, scheduled for May, is the first to use an updated design for the laptop. Noticeable improvements over BTest-2 include:
- A faster, lower power processor: the Geode LX-700
- 128 KB of L1 Cache, 128 KB of L2 Cache (vs. 32 KB of L1 cache)
- Faster processor and memory clock (433/333 vs. 366/266)
- 1.5 W typ. vs. 3 W typ.
- Much better graphics processor, including support for rotated blits and depth conversion
- More memory: 256 MB of SDRAM (vs. 128 MB)
- A new hinge design allows greater tilt of the screen
- An improved case design (addressing strength and water resistance)
A very small number of BTest-3 units (around a hundred) will be built, all destined for hardware and low level software development.
Beta Test 2 Systems (BTest-2, or B2)
Approximately 2500 systems were built by Quanta and are being distributed. These are fully functional machines with CaFE asic's, and reflect some, but not all of the learning and improvements from testing of BTest-1. Much more information about the BTest-2 systems can be found in the BTest-2 Release Notes. Some of the details of the hardware design are to support the OLPC Human Interface Guidelines.
BTest-2 systems are almost identical visually with BTest-1. BTest-3 will have more substantial physical differences. An easy way to tell the difference between BTest-1 and BTest-2 is that BTest-1 keyboards have white lettering, and BTest-2 has black lettering.
Beta Test 1 Systems (BTest-1)
Approximately 875 systems were built by Quanta and were distributed. These are fully functional machines, but built before the rigorous testing that will now take place. Much more information about the BTest-1 systems can be found in the BTest-1 Release Notes.
Pre-BTest boards
A small number of pre-BTest boards were built in preparation for building complete BTest systems. Developer information about B-test boards are here.
Alpha Test Prototype Electronics
Power up of the first OLPC electronics prototype boards occurred April 15, 2006. Power and ground testing continued over the weekend, and formal debug and BIOS bring up started Monday, April 17, 2006 at Quanta Computer's labs in Taipei, Taiwan. By Wednesday, April 19, Linux was booting on the first generation prototypes.

School Server Hardware
While the laptop is rightfully at the center of OLPC, a valuable peripheral is the school server. OLPC will be building and distributing school servers along with the laptops, to extend the storage and computation provided by each laptop, as well as providing a local library and a mesh portal to the Internet.
Unlike the laptop, the school server is more of a collection of services than a hardware platform. In a manner identical to the laptop, OLPC will collaborate with manufacturing partners to provide a cost-efficient hardware platform for running the recommended software. Unlike the laptop, the manufacturing collaboration will not be exclusive. Individual countries will be free (even encouraged) to design and manufacture their own school servers running derivatives of the OLPC school server software.
XS
This will be the school server built for OLPC by Quanta. It is still in the very early stages of design, but should reach early production volumes in late fall. See the specification.
XSX
This is a prototype school server, built for early school trials in country. It will be integrated from off-the-shelf components, and will be overpowered compared to a production school server in order to simplify early demands for system software. See the specification and the implementation.
