I had problems finding some desired stations on my radios 
where strong adjacent stations interfered.I marked the dial
with WHITEOUT on a toothpick to find them quickly.
 
I lost the green color on my 8 year old 25" Zenith TV.After 
trying to adjust the COLOR,I opened it up .I pulled off the
socket on the tube and noticed black spots on the pins.
I used some old DEOXID with a Q-tip and cleaned the pins.
Put back.Still no good.Noticed red,blue and green colored 
trimmer resistors on the socket board.So I rocked them and
put them back to the original position.Better but still not 
good.On the MENU,on the screen,had VIDEO SENTRY with 
choices PRESET and CUSTOM.So I put it to PRESET.
Now the color is a lot better.Don't know what I did.
 
I use a text editor on my DOS 3.3 386 with an ST251 harddisk 
to read all my E-mail from my Pentium II with XP.The ST251
finally died.Replaced the PC with a 50 MHz 486,Gateway 2000,
from Goodwill for $10.I'm using an EGA card with a monochrome
monitor .The EGA card had been intermittant on the 386
so I heated the bottom 4 " below a heat lamp until I 
could smell the hot bakelite and stopped.It's been 
working in the Gateway for 2 months now with no problems.
 
At Goodwill,I picked up a pack of strange floppies,KAO
brans,MF2DD,1 MB, with an offset slider .The slider 
opens toward the top of the floppy,not sideways like
the 1.44 MB floppies.Very unusual.Can't find anything in
google.Any ideas?
 
At Goodwill.I picked up a pack of 5 VERBATIM 128 MB 
Rewritable 3.5 " Magneto-Optical Disks for $5.
Tried Google.Saw 5.25" Verbatim disks of much higher
storage.Are these ZipDisks ? I noticed that Iomega
has stopped making the Jazz drive.
 
In repairing tapes from for our library,I acquired some tapes
from talking books,that have been magnetically damaged and 
were to be discarded.A book of 6 cassette tapes cost about $30.
When played,the volume would go up and down with a slight echo.
I thought of getting another copy of the book from the 
library,wiping out the bad tapes and copy from the good tapes.
BUT,the library says that this is illegal.There must be some
equipment in the library system of 10 libraries that is causing 
the damage.In one book,2 or 3 tapes would be bad quite often under
the bar code .When I watch the librarians use a scanner on the
bar code ,they hold it flat on the base of the scanner that looks
like a student lamp.
 
  I salvaged the tapes for my own use by cutting strips from
a Cork sheet and making little plugs for the write protect 
slots (easy to trim excess) and cover with Scotch tape.
I calibrated them with a counter on one tape recorder.A 120 
minute Maxell tape,gave 990 for one side of 60 minutes.
Then assumed;
   850=      55 min.
   800=      50
   750-780=  45 .
   700=      40
   624=      35
   510-540=  30
   260=      15
 
I tried to demagnetize the tapes with a 10 pound permanent magnet
but it didn't work.Then I used an old demagnetizer,Radio Shack,
Cat #44-210 Intermittent duty.One minute ON,20 minutes OFF to
prevent overheating.Worked fine.
