Inside the Gateway Connected Touchpad

Inside the outside of this month's Embedded Linux Journal is the Transmeta+Linux-powered innards of the new Gateway Connected Touchpad. To our knowledge it's the first ``Web Appliance'' from a first-tier PC manufacturer.

On it you'll find:

1. 400MHz Transmeta TM3200 processor (under the heat sink)

2. 64MB PC100 SDRAM

3. PCI Silicon Motion 710

4. POTS modem & phone jack (the RJ-11 socket)

5. BroadCom 4211 HPNA port (the RJ-45 socket)

6. Compact Flash slot (not accessable to the user)

7. ALI 1535 southbridge

8. Two USB connectors

9. 800x600 DSTN touch screen (on the far side of the board)

The keyboard has a wireless infrared connection. On the Gateway, the compact Flash is not accessible to the user. All upgrades--to the kernel, CMS, libraries, X and the AOL client 00--happen by themselves under the direction of the AOL client. AOL is using Mobile Linux v2.3.x for their client right now, but the upgrade mechanism allows them to upgrade to an image built by a newer Mobile Linux version. The browser is derived from the same Mozilla-developed Gecko engine used in Netscape 6.

One nifty feature is found in the lit power button under the screen. If you hold it down for several seconds, it turns off completely, and when you tap it again, it will do a full reboot. However, if you just tap it while it's on, the screen blanks out, and the CPU and memory go into a low-power state; then if you tap it again, it comes up immediately.
