Who wouldn't be smiling if they had a beautiful Mark 8 to feature at their computer exhibit? MARCH is proud to have received (on loan) an original Mark 8 computer for our computer museum. The system came to us from David Larson curator of the BugBook Museum located in Floyd Virginia. The Mark 8 was designed by Dr. John Titus and this particular Mark 8 was built by George Overfelt in 1975. The Mark 8 will be displayed within the MARCH vintage computing exhibit within the Infoage Science Center in Wall, NJ. Click image for larger view.
Herb Johnson tutors W. Lloyd Degnan on the finer points of HDOS BASIC. Herb restored and prepared this Heathkit H8 8080 computer system, with accompanying Heathkit H17 dual drive unit, for the event. Lloyd commented that working on the H8 was his favorite part of the show. Click image for larger view.
