FCO 2005 - AEH26 FileStore E01
Upgrade instructions
Ensure that the FileStore unit is switched off, and disconnected from the mains, the printer and
the FileStore E20 unit.
Prise off the back cover of the 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 the 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.
Remove the two side panels.
Undo the six screws on the underside of the unit which hold the cream coloured top metal unit to
the bottom metal unit.
Slide the metal top backwards and off the main unit.
Remove the power connection and 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
different FileStores, and it is important that this is put back on in the correct manner later.
Undo the four screws holding drive 5 to the bottom of the case.
Slide the drive forward, tilting it so that the back supports rest on the circuit board. This reveals
two Eproms, IC4 and 105.
Remove the Eprom in socket IC4 carefully, and retain it. Insert the new Eprom marked 0254,
204-03 in the socket, with pin one at the rear. Similarly, remove the Eprom in socket IC5 and
replace it with the new Eprom marked 0254,205-04.
Re-assemble the unit, following the disassemb|y 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 air flow.
Test the assembled unit by switching on with the front flap down, ensuring that the Mode light
remains on, then closing the flap, and checking that the unit enters user mode. If possible, check
using a computer that 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 two removed Eproms to Acorn (Spares department). Please return in anti-static foam with
pins intact, so we can reblow the Eproms.
