 Well, with the recent announcement of the Mega series, everyone of us is
concerned with what they're going to do with their 520/1040. 
Personally, and I am sure a lot of people will share this point of view,
I like my 1040 and would like to keep it, but won't do so if:

     1/ there is no ROM upgrade for it 
 or
     2/ its RAM can't be expanded to 4 Megs (with 1 Mbits chips)

Point 1/ has been already discussed extensively on this net. I will simply quit
Atari altogether if they don't release a new set of ROMs for the 520/1040.
I don't mind having to pay for them, either, nor do I mind having to pay for
the so long awaited 'ST Internals' docs. Just release them.

Point 2/ is another story. I must confess Atari took me by surprise by 
announcing their Mega ST so quickly, and I hadn't spent too much time worrying
about RAM upgrades for the 1040. But now, I'm ready to bet that 4 Megs will be
standard for professional ST applications in no time at all, and I don't want
to be left out without a piece of the action.
So the question is simple:

    CAN A 520/1040 BE UPGRADED TO 4 MEGS OF RAM ??

I know the MMU can handle it, but what about the rest of the system ? (ROMs,
power supply, wiring,...).

I would be thankful if somebody from Atari could provide a straight answer to
this question (Neil, Allan, Landon,...?). I'm sure this is of general interest.
And it'll save me the trouble of stripping down my 1040 to figure it out by
myself !

Thanks.
