I have a question that has probably been posted here many times. If there a FAQ for this type of questions, I would appreciate a pointer. We are in the market for a Word Processor, the likes made by Brother and Smith Carona. These come with propreitary word processing and spreadsheet software with an attached printer and sell for about $300. For the work we intend this the features are sufficient and the price is compelling. They operate on 110V, 60Hz supply voltage. We looked at models with LCD display as well as separate CRTs. We wish to take to this to India, where the supply voltage is at 220V and 50Hz. We could step the voltage down to 110 using a transformer. However, I am not sure if the frequency can be changed using a transformer. What type of damage I am looking at if the supply frequency stays at 50Hz when the part is rated for a 60Hz supply? Would CRT is more succeptible than LCD? And why? A friendly sales person at a local Radio Shack explained that PCs which have video hardware built-in or on an add-in card that drive the monitors are not really dependent on the supply frequency as the cards generate all the required frequencies for proper operation. Is this correct? Do word processors have similar internal frequency generators? The Customer Service departments of both companies have been of no help. I am posting this to pc, mac and market news groups because I am interested in buying a used PC or Mac for which I would have the same set questions. Thanks -- Sundar Iyengar sundar@mipos2.intel.com

Hi Sundar - When I was a student in Sweden (220V@50Hz), I brought over the then new IBM PC and monitor. I ran it off a transformer without any problems at all. /Per
