Hi.
The best way to know what is going bad with your computer is to test its parts
in a “know good” computer. Did you swap the floppy drive data cable?. Check it
for continuity; remember that there are data and power on it. Maybe power lines
are open. Also, check the voltages from the analog board power supply...
Rodolfo.
