Who built a computer that cared about AC frequency to drive the real time clock? Never heard of anyone doing that. Must have been a large machine given all microcomputers are fed DC from their power supply and have no clue nor care what the AC frequency was. -- Len Sorensen --- Talk Mailing List talk@gtalug.org https://gtalug.org/mailman/listinfo/talk
