[I related how my 850 printer interface stopped working, and that exchanging its power supply with that of my 800 computer had caused the computer to stop working as well.] In article:<111371@philabs.Philips.Com>, rfc@briar.Philips.Com (Robert Casey) [stated that a short in the 850 interface likely blew the fuses in both transformers, and outlined a way to repair them.] This opinion was shared by several other people who responded to me directly. As Robert pointed out, the fuse can be replaced IF you can crack open the transformer case, which is not designed to be opened. (I haven't carried out the repair yet.) ---------------------------------------------------------------------- The object lesson from this is that one shouldn't switch power supplies between working and broken components without checking out the broken component (e.g. checking for a short). ---------------------------------------------------------------------- Finally, a mail order source for new power supplies (info supplied by Frank E. Seipel): ------------------------------ American Techna-Vision 1-800-551-9995 415-352-3787 (California only) Cost is $14.50, 'Power Packs'. Also, they sell the '850 12pc IC set -- all except ROM ' from $19.50 ------------------------------ Thanks to Robert Casey for his post and the following people who mailed to me directly! Frank E.
