look, someone has reinvented the minicomputer architecture!

Yup! That is just too funny! Unfortunately I can remember the first mini's - both the skirts and the computers!!!! Thanks for sharing! David Nicol wrote:

I like their idea, but I think it's something that could be added in to Linux fairly easily with PCI video cards and USB devices. Once you work out a frame work of assigning particular groups of I/O to each other, start an X session for that group and off they go... Jon.

Try LTSP and their are many liveCDs, howtos and clients to make it work fairly painlessly. On 12/13/06, Jon Pruente <> wrote:

http://www.ndiyo.org/ They are building custom hardware for thin client terminals. They've got a prototype of an Ethernet based client, and are working on a USB model. And it all runs on FOSS. They're running a custom Ubuntu install to handle the client setups. The USB model, called Hubster is a great concept. It's better and more focused than what I mentioned previously. Run it all over USB and use a hub as the method of delineating what parts go together for each terminal. Also, because it's based on a hub centric model, each station can have an independent config based on need. There will be no waste of features for some, and no lack of features for others. The Hubster model sounds like a great way to go about it. Adding in more USB 2.0 cards will give more users per machine than slapping in more video cards. You simply aren't going to get 10 users per machine and give them their own video card with 3-4 PCI slots. And, the Ndiyo! people seem to want people to tae their idea and play with it for non-commercial applications. Great! Jon. On 12/14/06, Luke -Jr <luke@dashjr.org> wrote:

As long as you have the video cards, it should be pretty painless anyway. _______________________________________________ Kclug mailing list Kclug@kclug.org http://kclug.org/mailman/listinfo/kclug
