447.0. "Memory upgrade - 4 * 1meg chips" by BAHTAT::REID () Fri Apr 14 1989 04:18

    I am aware of the other Note on memory upgrades, but since it Atari
    have released another new board design on the unsuspecting public,
    the old note is nolonger true.
    
    I have one of the new design 520STFM's - instead of 16 *256kb chips
    it has 4 * 1meg (4/256) chips and to make things even more difficult
    they have switched to surface mounting. Has anyone upgraded one
    of the new boards to 1 meg yet and if so can they post details of
    the upgrade here.
    
    Thanks in anticipation.

447.1ari want you to buy a 1024UKCSSE::KEANEFri Apr 14 1989 05:0528
    
    Hi,
    
    I was one of the lucky ones, all I had to do to my 520 ST was to solder
    another row of 256 K chips on the top of the existing chips. I have not
    seen any info on anyone upgrading the 4*256K pack variant.
    
    However. Is there any signs of unused mounting pads for an upgrade. If
    you remember the 520stfm's prior to the new design had a complete set
    of holes ready to install the chips in.?
    
    If there are no available mounting pads then you would have to consider
    either making or buying an add on/in PC board.
    
    There is a plug in add-on memory board available from many dealers. I
    have an advert in front of me from E.A.Brown. this is a 1-4 M
    solderless RAM board. for original ST's . OH OH, reading the ad, it states
    you have to pull the MMU chip and the Video shifter out of their sockets
    and install them in sockets in the memory board. . I BET THE MMU AND
    SHIFTER ARE SURFACE MOUNTED AS WELL in your STFM. 
    
    Try giving Atari a bell in Slough, ask for Les PLAYER Atari Support
    manager, and give him a hard time..!!!
    
    Sorry I dont appear to have much help for you.

447.2Upgraded in half a day.BAHTAT::REIDTue Apr 25 1989 10:0410
    
    I have just had a call from the 16 bit centre in Harrogate 0423
    531822. They have just upgraded my machine in half a day for 120
    pounds. As the chips are 28 pounds each that only 8 pounds for labour.
    They also turned it round in under half a day.
    
    I am now the owner of an 1040STfm without the badge.
