Also what was the display device? --------------------------------------------------------------- Yes, virtually all the Control Data systems displayed octal. The devices were varied, from projection displays (1604) to CRT vector drawn (6600). Some, such as the 8090 and 8092 had optional front panels to display either binary or octal. Octal use continued at CDC up through the 1700 machine, which was hex. Seymour finally went to hex on the Cray series. Here's a question for the list - how many still have and use the TI calculator that could be used in octal or hex? Billy
