== OMAP Processor families ==
 
 
<pre>
 
Per the TI website, the OMAP families are broken into "High Performance", "Basic Multimedia", and "Modem and Applications".
 
 
"High performance"
 
 
OMAP1
 
 
    * OMAP1710 - 220 MHz ARM926TEJ + C55x DSP
 
    * OMAP1621 - 204 MHz ARM926 + C55x DSP + 2MB Internal SRAM
 
    * OMAP1612 - 204 MHz ARM926TEJ + C55x DSP
 
    * OMAP1611 - 204 MHz ARM926EJ-S + C55x DSP
 
    * OMAP1610 - 204 MHz ARM926EJ-S + C55x DSP
 
    * OMAP1510 - 168 MHz ARM925T (TI-enhanced) + C55x DSP
 
    * OMAP5910 - ARM9 + C55x DSP
 
    * OMAP5912 - ARM9 + C55x DSP
 
 
OMAP2
 
 
    * OMAP2431 - 330 MHz ARM1136 + 220 MHz C55x DSP
 
    * OMAP2430 - 330 MHz ARM1136 + 220 MHz C55x DSP + PowerVR MBX lite GPU
 
    * OMAP2420 - 330 MHz ARM11 + 220 MHz C55x DSP + PowerVR MBX GPU
 
 
OMAP3
 
 
The OMAP3 is broken into 3 distinct groups: the OMAP34x, the OMAP35x, and the OMAP36x. OMAP35x is a variant of OMAP34x intended for open source development, and the OMAP36x is a 45nm version of the 65nm OMAP34x with higher clock speed.[1]

    * OMAP3620 - 720 MHz ARM Cortex A8 + 430 MHz C64x+ DSP + PowerVR SGX530 GPU + ISP (Image Signal Processor)
 
    * OMAP3610 - 720 MHz ARM Cortex A8 + 430 MHz C64x+ DSP
 
    * OMAP3530 - 600 MHz ARM Cortex A8 + 430 MHz C64x+ DSP + PowerVR SGX530 GPU + ISP (Image Signal Processor)

    * OMAP3503 - 600 MHz ARM Cortex A8
 
    * OMAP3440 - 800 MHz ARM Cortex A8 + PowerVR SGX 530 GPU + 430MHz C64x+ DSP + ISP (Image Signal Processor)
 
    * OMAP3430 - 600 MHz ARM Cortex A8 + PowerVR SGX 530 GPU + 430MHz C64x+ DSP + ISP (Image Signal Processor)
 
    * OMAP3420 - 600 MHz ARM Cortex A8 + PowerVR SGX 530 GPU + 430MHz C64x+ DSP + ISP (Image Signal Processor)
 
    * OMAP3410 - 600 MHz ARM Cortex A8 + 430MHz C64x+ DSP + ISP (Image Signal Processor)
 
 
OMAP4
 
 
    * OMAP4440 - 1+ GHz dual-core ARM Cortex-A9 MPCore + PowerVR SGX 540 GPU + C64x+ DSP + ISP    * OMAP4430 - 720 MHz dual-core ARM Cortex-A9 MPCore + PowerVR SGX 540 GPU + C64x+ DSP + ISP
 
"Basic multimedia"
 
 
    * OMAP331 - ARM9
 
    * OMAP310 - ARM9
 
    * OMAP-DM270 - ARM7 + C54x DSP
 
 
"Modem and applications"
 
 
    * OMAPV1035 - single-chip EDGE
 
    * OMAPV1030 - EDGE digital baseband
 
    * OMAP850 - 200 MHz ARM926EJ-S + GSM/GPRS digital baseband + stacked EDGE co-processor
 
    * OMAP750 - 200 MHz ARM926EJ-S + GSM/GPRS digital baseband + DDR Memory support
 
    * OMAP733 - 200 MHz ARM926EJ-S + GSM/GPRS digital baseband + stacked SDRAM
 
    * OMAP730 - 200 MHz ARM926EJ-S + GSM/GPRS digital baseband + SDRAM Memory support
 
    * OMAP710 - 133 MHz ARM925 + GSM/GPRS digital baseband

Specifications
 
416MHz PXA-270 XScale processor
 
64MB RAM
 
128MB internal flash memory
 
640x480 16bpp backlit LCD touchscreen display
 
Input methods: keyboard, stylus with handwriting recognition
 
Ports: IrDA, USB (host & slave), headphones & remote, Zaurus connector, SD memory card slot, CF slot
 
 
Unlike the C3000 and C3100 units, there is no internal hard drive. A microdrive can be installed in the CF slot. I chose the C1000 specifically because it did not have a hard drive, since I worry that a hard drive subjected to a lot of handheld use would be prone to failure, especially if dropped.

Unfortunately, I can't confirm much. In hho CVS there should be
 
sort-of support for sleeves. I tested it with dual PCMCIA sleeve, it
 
worked (tested with orinoco gold wifi card and some pcmcia ethernet
 
adapter).
