NCD 19r monochrome Xterm

Hi, all, I have the opportunity to pick up a couple of NCD 19r mono Xterms locally, if I want (someone else declined due to lack of basement space). I have not tested them, but I can. Doing a bit of digging, I see that folks have offered them on numerous mailing lists over the years (including suns-at-home, and I think here) and frequently get no takers, so it sounds as if they have no assignable cash "value". Does anyone here have any experience with them, how hard it is to find the software for the tftp repository? (I did a non-exhaustive search and haven't found any yet) Besides performing their obvious function (serving a mono framebuffer, mouse, and keyboard), are they neat in any way, or are they part of the dustbin of history? They are kinda large, so I'm not exactly eager to move *more* large CRTs into my house without good reason. I'm seeking a reason. I already have an HDS xterm that I got working some time back, but it's just a slab - you use your own monitor. *That* doesn't take up too much space on the shelf. A large glass bottle does. Thanks for any input and/or stories about the NCD 19r. -ethan
