[comp.sys.amiga.tech] Frazzled Amiga 1000 - Repair Advice Sought

whorfin@pixar.uucp (Beware of programmers wearing grounding straps.) (08/10/89)

During a recent art installation opening, a clumsy cheesehead plugged the
serial cable into the disk port.  It didn't fit, but it fit well enough
to bust things.

The symptoms:
The amiga wouldn't boot.  It would only play the first 4 notes of its "happy
melody".  Some time later, I took it home to operate.  First 4 notes.
Swapped the 8520's.  Last five notes only, no boot.  I didn't remember the
significance of the notes, having long since forgotten both that and
the significance of boot-failure colored screens, but figured an 8520 must've 
been fried.  "They're always the first to go."  So, I bought a new 8520.

Some weeks later, the 8520 arrives.  I turn on the Amiga to confirm the
previous behavior, only now it plays the whole melody, but refuses to
accept Kickstart.  By ejecting and reinserting kickstart, rebooting and
power cycling, I get it running long enough to check the disk drive
speed.  Seems OK.  But, now it won't boot at all.  It either goes to
a yellow screen, or continually refuses to accept kickstart.  If it manages
to read kickstart, I get as far as loading workbench, at which point it
gurus back to kickstart.

Replacing either of the two 8520's does nothing to change this 
behavior.  What's up?  Suggestions?
