*====*› Excerpt  of a letter received from our› member SAM CORY and 8BIT Librarian for› J.A.C.G., in New Jersey ......›› THE PROBLEM›      "Of  importance  to  you  is  the› inverter  supply  in  the basement. It› incorporates my favorite answer to two› computer  problems. From the batteries› I   will  run  zener  regulated  12VDC› supplies to my computer system on  the› second floor. This will be my constant› supply to eliminate any  heat  in  the› computer    system    from     voltage› conversion.  It  separates my computer› from the power line outages and  trash› on the power lines. The batteries make› a wonderful noise sink. ›› REPEAT OF A PRIOR SUCCESS!›       I   had   this   battery  system› operating at another location for some› time  with  a 12v bat in series with a› 6v bat to ensure  enough  voltage  for› the  12  regulators.  I will have that› here. In addition all AC and DC  lines› into  the system will go through surge› and interference  networks.  Batteries› are kept at proper charge by a sensing› charger.  I  have  added  a  switching› circuit which alternately charges  the› 6v and 12v bats.›› NOTHING IS PERFECT!›      The  only  hole in the system was› through the modem. I fear it  suffered› from  a surge and has gone to computer› heaven. I have a cousin who because of› the same mistake, lost his modem, 850,› 810,   800   system.   I  should  have› learned. ›› WARNING›      DO NOT let anyone  tell  you  the› phone  lines are safe even though they› put  in  fuses.  The  period  of  time› before the fuse goes is plenty to kill› a system.›› WHAT TO EXPECT›      The  inverter  will   supply   my› MONITOR,  VCR,  and TV. I did not have› the   inverter   before.   With   this› additional    circuit    I   will   be› completely free from the  power  lines› at  all times thus ensuring no loss of› a clock, or  interuption  or  loss  of› files  also.  By the way, it also will› supply enough power for at  least  one› 100w  lamp.  Not  enough power to have› hot tea, or cocoa.›› PROBLEM SOLVED!›       I   found   in   the  past  this› completely cured  the  most  prevelent› problem  I  have  had  from  the  1050› drives.  I have 3 1050 drives down and› 2 more that die  when  the  room  temp› goes  up  which  I am sure this change› will solve. At least  it  has  in  the› past.  You now know one reason for the› inverter. The other is obvious. I  sit› at  the end of a power line and a very› old farm system with  old  wiring  and› lots of tree overhang, which cause all› kinds of problems.›› SOLUTION FOR WHOM?›      Admittedly, these  solutions  are› not  for  anyone excepting a dedicated› 8-bitter.   Lots  of  cash,  a  goodly› amount of time, and a fair  amount  of› technical  information.  Not  for  the› faint of heart......... ›› (Editor...Thanks  SAM for sharing your› problem and solution with us. A.P.)›                *<>*<>*›
