        Hi there, all you guys in NetLand ...



        The  holidays  are  over and Commodore has launched the A4000.  I'm
interested  in  buying such a beasty, but before I do that, I would like to
see a few questions answered ...

        If  I'm  correct, the performance of the AA chip set depends on the
type  of ram chips you use for your CHIP ram.  Is this true ?  If so, could
anyone  please  tell  me exactly what this means and with what kind of CHIP
ram the A4000 comes with out the box ?

        It  seems  to  me that all custom chips now have 32 bit data-busses
(That's  what  it  says  in  the  German  Amiga  mag.), however in the same
article,  the  Amiga  mag.  claims that the copper has not changed ...  Can
someone please enlighten me ?

        The  A4000's display can range upto 1280x512 (maybe higher, I don't
know), but the question is :  is this interlaced ?  I have read that the AA
chip  set  can  produce  non-interlaced displays, but can it do this in all
these  resolutions  ?   Is the 640x960 productivity without flicker ?  This
would  mean  that they would use 62KHz if I'm not mistaken ...  Let's see :
normal 640x200 -> 15KHz, productivity 640x480 (non-interlaced) -> 31KHz, so
if  the  640x960  would  be  without flicker, it would have to have a 62KHz
frequency,  isn't it ...  Again can anyone explain this to me/correct me on
this ...

        There's  no  SCSI  on  the  A4000  and if the German Amiga Mag.  is
right,  some  SCSI  controllers  would need new drivers for the A4000.  Can
anyone  tell me which SCSI controllers will work correctly on the A4000 and
which won't.

        I've  also  seen  an  add for the DOMINO graphics card from X-Pert.
Are  there  people  who  have this card ?  If so, what do you think of it ?
And  more  important,  would  it be useful to add such a card to an A4000 ?
Will  it work ?  DOMINO seems to be a 72Hz flicker fixer as well as a 32768
colour graphics board.  Is it useful on an A4000 ?  Those 32768 colours, is
that  true colour ?  I mean, can any pixel have any of those colours ?  All
info is welcome.

        What  kind of a monitor comes with the A4000 ?  Is it a 1960 ?  Can
this monitor also be hooked up to the DOMINO board (1024 x 768 at 72Hz) ?

        I  would  also  be buying a Syquest 88MB or a floptical unit.  What
would be the best one ?  The Syquest has more space on a single medium, but
a floptical is cheaper.  I guess the Syquest is faster, but I'm not sure of
that,  since  I haven't seen any flopticals around here yet ...  Again, all
info is welcome ...

	I've  seen  some  postings here that Commodore would be putting in
on-board  SCSI,  a  DSP  and  16-bit  sound  by X-mas.  Ok, I know this is
advocacy,  but I really would like to get something for my money, so could
someone  please  tell me if this has been confirmed or at least heard from
several independant sources ?

        And  as a last question :  will there be an A4000 Tower ?  Does the
A4000 have enough free space to install a Syquest ?  (They told me that the
A3000 didn't).
