Re: Advantages of Parallel Hz
Homebuilt Computer Hardware Discussion of homebuilt computer hardware (alt.comp.hardware.homebuilt). Postings may deal with real hardware, or absract concepts, and are not restricted to any specific cpu or architecture. Topics may also include homebuilt peripherals added to existing off the shelf systems, or hardware hacks to existing systems/accessories.

It doesn't. As I understand it, heat is generated by transistors mainly during switching, i.e. when it's doing something. |
Look at Figure 2 in this Chip Design Magazine article:

Seems like a step backwards but certainly solves many of the usual support problems. Etherboot or Intel PXE for the terminals is a possibility if the hardware supports it or could boot off a usb disk or flash card. Thanks. Very nice. There are some decent thinclients available. Mostly looks like for internet cafes, classrooms, workrooms. A bigger market might be "standalone" thin clients. Home internet appliances with built-in browsers, but otherwise no programmability (state retained). Certainly more than the 32 MB LTSP minimum, but probably not more than 128 MB RAM. US$50 plus monitor (or S-video out for exhibitionists/remotecontrol-hogs who want to surf on the TV!) Such a device would be attractive to non-computer experts (nothing to go wrong) or as second PCs in a household. -- Robert Add an HDMI output to that for all the large wide-screen types. The added resolution is quite worth it. |
Not with the range of devices they're talking about.
Any geek can say 'add this newer tech' but where does it
END? It doesn't, if the quest is neverending upgrades to
supprot the latest thing, it's a treadmill that defeats the
purpose.
There is no need for HDMI, today the supportive OS and CPU
or video card to accomplish this are going to negate the
minor benfit of it being a client that merely lacks mass
storage otherwise.

disk after it has been formatted. It's way expensive, but it can be
done. The problem is that the head is never positioned in *exactly*
the same place and the track has finite width. Some of the magnetic
flux at the edges of the track may not be erased.

With an electric chip it is much easer to permanently remove confidential data. COWSHIT! |
