Legacy X-Terminal Software?

Feren asks: "While working on a project for a non-profit organization I'm involved with, I recently acquired a batch of Sun Microsystem "XTerminal-1" machines, along with one or two Tektronix machines. With the Sun X-terminals I've been able to kludge together a sort of working system to get them to boot and run X, although when I read Sun's documentation, they talk about such things as the 'Xserver jumbo patch' or 'SPARC Xterminal(TM)software version 2.0' as being a better way to make them run. Yet I can't find this software anywhere, and the Sun rep I speak with regularly at my real job is just as clueless as I am about these devices and their software. I have the sneaking feeling these products hit their EOL (End Of Life) quite some time ago. Similarly I cannot find any information on where to locate/download/purchase software for the Tektronix boxes. Has anybody ever gotten ahold of this elusive software? Has anybody ever considered building a site for legacy X devices such as these, like a repository for software?"

"I know the software licenses used to be a huge boon to the Xterminal manufacturers, but since most of them aren't supporting these devices anymore (nor even have spare copies of documentation or software to sell individuals like myself) I wouldn't predict there being a great deal of trouble in obtaining permission to post this software for general consumption, so long as there was no charge to retrieve it.

Would there be any interest in such a site or repository if it was created? Does anybody know where to get the software to run these machines? Granted, they're not fast or the latest word in thin-client, but they are still usable and relatively cheap to acquire... if you can only find the software to make them go."
