I just got my new Rev. 6 A2000 myself, and while I *LOVE* the 1 MB
Chip RAM, it seems as if the machine is not as stable as my old
Rev. 4.4. Very often the machine Gurus on bootup, much the same
as Steve described above. I have the original A2090 with a Rodime
40 MByte SCSI HD. A friend of mine has experienced similar problems,
in fact, it looks as if his 2 MByte RAM Card (also the original
Commodore Expansion, I don't remember the model) doesn't work
properly with the new Rev. mainboard (the machine becomes *VERY*
unstable and crashes frequently, i.e. when Zoo is started), while
it works perfectly with a Rev. 4.4 board.

>From the experience I have (ok, ok, so it is based on only two
samples of the new board) I can only *WARN* people not to get stuck
with the current Rev. 6 board. While it looks tempting at first
sight, it seems like a real bummer to me.

Could anyone from C=A clarify what has been changed on the new
mainboard? What for example is the upside down piggyback PCB near
Agnus for? Has the bus timing changed and is it possible that 
older expansion boards don't work? I (and I am sure quite a few
people) would appreciate any comment. Dave, are you listening?
