Date: 25 Mar 1982 1714-PST Sender: OLE at DARCOM-KA Subject: Singmaster and IBM From: Ole at DARCOM-KA (Ole J. Jacobsen) To: Cube-Lovers at MIT-MC Message-ID: <[DARCOM-KA]25-Mar-82 17:14:12.OLE> Singmaster has as you probably know set up his own company selling cubes and other puzzles of all shapes and sizes. The latest price- list includes Rubik's Calendar Cube, a true Executive Toy. The object is, if I understand it correctly, to get one or more faces displaying the correct date/month. He also sells Braille cubes,- Ideal cubes with raised dots. His "Cubic Circular" as mentioned by Stan, is well worth getting, as it contains alot of interesting information. A Marketing Consultant from IBM gave me a cube which has IBM4331 printed on all the six center faces and the words: Value,Function, Support,Reliability,Performance,Productivity on each facie of each face respectively. The orientation of the IBM 4331 relative to the other 8 repeated words on each face makes it a supergroup variety. In my opinion, this cube is the best product to come from IBM in years!
