This is quite a find! Thanks for posting this. Really a lot of work by the IBM people to produce just what, a half dozen actual computers?

The power of this computer seems roughly comparable to the Olivetti Programma desktop computer, which was produced at about the same time and was commercially available -- and of course the packaging was much slicker. It has been mentioned on HN many times:

This post links to the Programma 101's architecture and internals, which you can compare to the article linked in the original post.
