I had an Amiga 1000 back in 86. Sure, the one fan was quiet, and there was no HD, but the floppy drive made a rather loud grinding noise. The Mac Plus, SE, and the like at least had a nice "blip"-sounding floppy.
Actually, I believe that the GPL and Open Source model are based on capatilistic ideas -- the dominant one being intelectual property. In a capitalist system, the GPL is a great way to release intelectual property to the general public without losing property rights to it. GPL preserves copywrite protections for the author, which are based on the idea that the author owns the work in question as a product of his/her labor. Get rid of the idea of personal/private property ownership, and the GPL is useless.
I got a Color Fujitsu Stylistic 1000 on Ebay for less than $250. It's got a 100MHz 486DX, 8 inch backlit LCD, 3PCMCIA slots (one for the HD), and is supposed to run linux without any trouble (see http://www.linuxslate.org). I got a Fujitsu Point 510 (AMD K5@100MHz) with a 10-inch color LCD for under $350 at Ebay with similar specs.
Look around, there out there!
how many tons does 4-mile-long umbilical cable weigh anyway (one that is strong enough not to break under its own wieght)? Usually deploying a deep sea submersible requires heavy-duty cranes and handling equipment.
The datasonics/benthos technology currently uses MFSK with frequency diversity (i.e. multiple tones used to represent a single bit) and noncoherent detection. The underwater acoustic channel at these ranges can really only support about 20 KHz of bandwith, which doesn't leave much of an expansion factor for spreading for a 2400 bps link. Benthos is looking at frequency-hopped spread spectrum for their next-generation modems. There are several other companies developing spread spectrum acoustic modems for the navy using direct sequence spread spectrum and DPSK modulation.
From the sysbom.xls listing in the design specs, the display is an Epson part number TCM-A0822-xx, and the touch screen is a Dynapro custom part, pn 9271. I checked websites for both companies with no luck finding any info on these. Also, all the documentation is for Itsy version 1, but one of the slide presentations shows an Itsy version 2, which is smaller and uses Li-ion batteries. The Itsy v.2 looks even better, so I would hold off until Compaq releases the v.2 design specs. You may be better off trying to build a LART ( http://www.lart.tudelft.nl/index.php3 ), which is truely GPL'd (open design) and already has a group of people offering PCBs), or just waiting for Yopy.
