[misc.wanted] Wanted: AT&T 7300 power supply

wechsler@leah.Albany.Edu (Steve Wechsler) (03/31/89)

A friend of mine has an AT&T 7300 pc with a dying/dead power supply (it
only works when he turns the PC upside down, and it's then erratic at
best).  He can't afford to buy a brand new one (at least, not at the
price that was quoted by a local computer store) and repair would be
pretty expensive also.  Does anyone out there in net.land either have a
7300 that they're parting out, or know where an inexpensive replacement
can be obtained, or even know if there is anything in particular that
goes wrong with these things (we took the thing apart last night,
nothing was visible to the eye)?

Please reply in E-mail only...

Thanks in advance.

This is a long shot, but you might try this:
After taking my 7300 apart a few times, I ended up with a system 
that only worked with the cover off and failed with it closed.  
It finally turned out that several of the solder joints had
failed where the connector to the ribbon cable is soldered to the power
supply.  After resoldering, everything worked fine.

If you are going to trash the supply anyway, it wouldn't hurt to re-solder
everything.  Your problem sounds like a mechanical interconnection
problem.
