[comp.sys.amiga] Injured Amiga

Last night, I unplugged my modem from the serial port while the computer was
on.  Since, then, neither the serial or external drive ports are functioning.
Does anyone know if I blew up a board, a chip, or what???
The external drive port is not totally destroyed, because the computer comes
up with "disk in DF1 not a DOS disk" - but, the drive never checks the disk.
Any info?
thanx

Really, how surprising... :)

You blew an 8520, in all likelihood.
Please use followupto group next time, 'kay?

	You've blown one of the 8520 chips.  See your dealer for a replacement.

	They are VERY static sensitive, you should have the dealer do the
	replacement if you're not familiar with the proper procedures.

Sounds like you blew one of the 8250's.

This happenned on mine when the diskinserted line no longer functioned
Try using DISKCHANGE, which may fix it, at least as a temporary
solution.

Jonathan, try the CIA's (8520)'s switch them and if the ports begin to
work purchase one from your local dealer...it is possible for both of
them to be bad....Mike
