Title: Emulator II - start problem Post by: dvdborn on April 02, 2008, 01:47:56 AM The floppy reader clicks three times, the machine displays "This will take a while" or "Boot in progress" and sits there forever.
BE CAREFULL, THIS IS DANGEROUS. TAKE AWAY the power plug from the machine. Open it and take the power supply away. You will see that the connector (the one with the yellow, red wires that distributes the power to the boards and the floppies) may be brown, burned at the location of the yellow wires, wich is the +5 volts. Idealy, this connector shoud be changed. If you can't, just clean it by putting some contact cleaner on it. Now, if you take an attentive look to the solder side on the connector pins, you will find out that the solder is crackeled. By using a solder pump, take away the bad solder and take away the connector. Using a blade, scratch the varnish off the board (near the holes of the connector) in order to increase the surface of the soldering on the copper layer of the board. Clean everything. Clean the pins of the connector. Solder the connector back in place, put A LOT of solder on it but be careful that the solder doesn't come in contact with the right angle metallic plate when you put the power supply back in place onto it and as well, be sure you are not shorting some connector pins ! VERIFY EVERYTHING before soldering, while soldering, after soldering and verify your verification !!! Put the power supply back in place, do not forget to put back the two wires of the voltage selector, neither the connector with the wires. CAUTION : an "unloaded" E2 power suplply wil BLOW INSTANTLY if you forget to put back ALL the connectoirs in place. It will now work for years to come.
