Ah, you're right. It's been years since I saw one ^_^ I had confused the Knight TV keyboard with this one. It had less keys, but more ITS-specific keys like backnext, a ^Z key, and a colon key. It just looked messier to me. (ITS commands started with a colon. ^Z was like ^C in UNIX, except instead of killing your program it would transfer to its superior, which was usually the DDT debugger. I guess it's like pressing ^C when a program is running inside of gdb.) There's one of those pictured at the website too, for comparison.
You had my hopes up for a second. CADR was an awesome machine, albeit slow. It should have survived PCs but just didn't have a market in the DOS era. They made a comeback when object-oriented code caught on, but it was too little, too late. Windows XP implemented in LISP with hardware GC would probably kick much ass. Sadly, it wasn't to be, and we have the current C++ train-wreck.
