I bought a used NCD X terminal from a guy at a computer show for $40 last weekend. It looks really cool, but it boots over the network and I don't have a boot image for it (its software was not in the box). I couldn't care less about the whole NCDware package, I just need the file "Xncdecx" to make it boot ...
The same bunch of people also sold me a copy of Alias-Wavefront Studio 8.0 (with about 16 inches of documentation) for $2.50 (!!!!) - too bad I don't have an SGI to run it on. :(
They said they had a working PDP-11 system. I would have loved to see that.
