You probably popped one of the 8520 I/O chips.  The one (U6P) that supports
the printer port also senses a number of the floppy control signals.  There
is raw +5 volts on one of the connector pins, that can damage the chip if
shorted to one of the other pins.

Convince your service facility to try swapping out these chips before swapping
the main board.  They are socketed in most all systems, and you should save
a pile of money.

It is *NOT* a wise act to plug or unplug the video, floppy or printer
connectors when the machine is powered up...  Those little sparks you
see are a warning 8-)
