Every time my refeigerator turns on and off I am afraid I am frying my CPU or putting potholes in my hard disk. Are these fears founded at all ? Should I buy a surge protector ? Does anyone have experience with these things ? There appear to be several types, including a strip like thing for about $20, which I could spring for if it does something useful.

Generally, refridgerators are on separate circuits than the rest of the house, and on a dedicated circuit (same as washer/dryer). If you insist on worrying about something causing a surge and damaging computer equipment, worry about the coffee maker or microwave oven or toaster. Even that is probably wasted worry, though, since most houses have separate circuits for the kitchen than for the rest of the house. The cheap surge protectors are simply an extension cord with a couple or three MOVs (metal oxide variable resistors) jumpered between the power leads. This is supposed to channel off the excess voltage (current?) to the ground lead. I don't have any experience with them. -- Tim (radzy) Radzykewycz, The Incredible Radical Cabbage.

Could anyone out there in net-world suggest a good and inexpensive surge protector/noise filter for use with a PC/XT system. I bought something from "Powerguard" but it blew up with a bang - fortunately I had not switched on my computer and the company was saved from my lawsuit! I am looking for something in the under $150 range. Information on UPS - Uninterrupted Power Supplies - would also be appreciated. Thanks. Irfan Ahmad eco10125 Bostonu - - - - -

I don't suppose anything else in your domicile was affected? You can't buy a UPS for an XT with a hard disk for less than 150. A real one (several minutes of backup power and actual sine wave output) will be more than $500. --Chuck -- - - - D I S C L A I M E R - - - {ihnp4,fortune}!dual\ All opinions expressed herein are my {qantel,idi}-> !intelca!cem own and not those of my employer, my {ucbvax,hao}!hplabs/ friends, or my avocado plant. :-}

There are some nice units sold under the Tripplite brand that include both filtering and surge protection. You can get them through some of the DP/WP supply catalogs or at Electrical/Electronic wholesalers. Seems the me that the price was in the range ~50-100 dollars depending on the number of outlets provided... -- George Robbins - now working with, uucp: {ihnp4|seismo|caip}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
