FCO 2014 -Upgrade Instructions AEH35 FileStore E01s and AEH26 FileStore E01 Ensure that the FileStore E01S (or E01) unit is switched off, and disconnected from the mains, the printer, and any other FileStore units. Prise off the back cover of the E01S (or E01) unit. It is easiest to pull this backwards and downwards. You will need to pull it quite hard to move it. Similarly, remove the front panel, complete with front flap. You will not be able to remove this completely without removing the LEDs, but it is not necessary to remove the front panel completely in any case. NExt remove the two side panels. Undo the six pozidriv(TM) screws on the underside of the unit which hold the coloured top metal unit to the bottom metal unit. Slide the metal top backwards and off the main unit. For the FileStore E01s unit, remove the EPROM in socket IC7 carefully, and retain it. Insert the new EPROM marked 0282,008-02 in the socket, with pin one at the rear. For the FileStore E01 unit, remove the power connection and the data connection from drive 5 (the one closer to the middle of the circuit board). Note carefully the alignment of the data cable as this may vary between FileStores, and it is important that it is put back in the correct manner. Undo the four pozidriv(TM) screws holding drive 5 to the bottom of the case. Slide the drive forward, tilting it so that the rear support pillars rest on the circuit board. This reveals two EPROMs, IC4 and IC5. Carefully remove the EPROM in socket IC4 and retain it. Insert the new EPROM, marked 0254,207-03 in the socket, with pin one on the rear. Similarly remove the EPROM in socket IC5 and replace it with the new EPROM marked 0254,208-03. Reassemble the unit, following the disassembly instructions in reverse. Ensure that the connections are made from the front panel to the circuit board connectors, as these may have been removed when removing the front panel. Ensure that the grating on the top unit is situated at the front of the machine when assembled to keep adequate airflow. Test the assembled unit by switching on with the flap down, ensuring that the Mode light remains on, the closing the flap and checking that the unit enters user mode. If possible, check using a computer that a communication is possible with the computer. Remember that you can just connect a computer fitted with an Econet interface to the FileStore - the FileStore will provide the necessary clock signal. Return the removed EPROM(s) to Acorn (Spares Department). Please return in anti-static foam with the pins intact, so the Acorn can re-program the EPROM(s).
