Cohen asks: > Why would a designer place a disposable/exchangable part > (such as a fuse) deep inside a 'sealed' assembly that has > existing external connections? > The fuse in fact has exactly the same status as every other part in the power supply, it is NOT a user exchangeable part, and is there as a safety device required in order to meet FCC, FTZ etc. regulations. It is not expected to blow any more frequently than any other component in the power supply. The complaints about the generally poor design of the mechanics of PC's is however all too justified, and cannot all be explained away by the "design down to a cost" that drives most PC designs. -- Ray Dunn. | UUCP: ..!uunet!philmtl!ray Philips Electronics Ltd. | TEL : (514) 744-8200 Ext: 2347 600 Dr Frederik Philips Blvd | FAX : (514) 744-6455 St Laurent.
