Summary: seems to be no ghosting on newer A1000 keyboards


I've seen a couple of different versions of the A1000 keyboards.
Someone said that the "problem" was fixed a while back.  The ROM
kernel manual discusses ghosting.  You'd have to hit pretty weird
combinations of keys-- something like d-f-j-k all simultaneously to
cause a ghost character.  I've never seen it on my machine at home,
which dates from October 1985.

I suppose there is an outside possibility that you could see a
glitch on a game that used the keyboard for motion control... but
we all only use our machines for serious C hacking, don't we? :-)

OK, here's my $.02 worth.  Everybody is talking about fixing up the
video.  How about some niftier sound while we're at it?  I'd be
kind of neat to have 12 bit resolution with a 30KHz sampling rate
on the DMA channel.  (I know, 3 bytes/stereo pair is kinda weird,
but hey... I thought 16 bits just isn't practical in a consumer
oriented machine, as 16 bits would require much fancier power
supply bypassing, laser trimmed chips, etc.).  By the way, the
current DMA sound channels on the A1000 are really nifty-- much
easier to deal with than the Ensoniq chip in the Apple II/gs or the
more primitive Mac technique.  You definitely did this one right
for a starter C-A.
