Thanks, Kit, for posting a notice of the Swap Fest!
 
I would like to add that Bob Brodie is no longer (just) tentatively
scheduled to attend - he confirmed in conference on Delphi last week
that _he will be there_.   (I also asked him what he will be showing:
he said: Portfolio, Stacy, STE, but probably not TT.  Maybe he will be
able to bring one anyway - but TT or not, the SwapFest should be interesting.
One more thing - Bob Brodie is scheduled to give a presentation (talk?) at
10:30 am and again at 1:30 pm, according to the latest news I've seen.

        To the authors of Gemini:
 
                I think I isolated the bug created by sbreak...  Maybe you
        did too, but it has to do with the mouse being moved after a graf_
        mouse(M_OFF,0) instruction is called.  Somehow when the mouse is
        turned back on, the mask is not drawn at it's new location, but
        at the old one (had the mouse stayed in place after a M_OFF).

Yes.
 
It is possible - and pretty cheap - to connect an OMTI controller for
the XT to the DMA Port.
 
But it's incompatible to everything: the DMA Port is blocked by this
thing, and it needs a special driver to run which is availeble only for
TOS (rumor has it that a minix-ST version is availeble too; rumor has
it, that rumor is just rumor...)
 
Well, if You can afford it: go for SCSI: SCSI devices will be usable in
the future, the SCSI host adaptors for the ST are more or less
compatible to the SHxxxes etc.

Is er iemand die mij aan een DMA-chip voor mijn Atari-ST kan helpen?
Ik denk dat het ding kaduuk is.

So far it's holding up.  But I am having intermittent video glitches
that may or may not be related to the clip.
 
I agree with you, the clip looks extremely lo-tech.  I was expecting
something that really cliped on, not just slipped over the pins.
 
I *really* put a lot of pressure on the clip's pins to bend them in
(before I put it on the 68000, of course).  My first few attempt didn't
work.  The hard part is bending the pins evenly so they all apply the
same pressure.

I'm considering soldering the four corner pins to hold it in place.  I
managed to pop it off once while attempting to ensure that it was
seated.  This caused me some excitement since the ST was on.

I tend to agree.

I have spent many hours trying to get the thing working, often ending
up by being *certain* that something other than the clip was at fault.
 
The trick is to bend the pins on the clip well inwards and then make
certain that the two rows are *dead straight*. A single pin out of
alignment and it will not work at all.
 
Once you have done this it will stay clipped on and (in my case), working
through fairly rough handling.

Message-ID: <1990Apr11.234810.11839@agate.berkeley.edu>
 
Instead of splitting up the group, how about adopting a keyword
like "TECH:" in the subject line.  Or perhaps in the Summary line.
Or hey put it in the keyword line!
 
The advantage of the subject line is the I know how to eliminate
the non-TECH: articles.  Perhaps there is a better way.

One of the main reasons for splitting up the group is so that the
people who are interested in just tech discussions (and there seem
to be quite a few) won't have to wade through the other stuff.  If we
just use a keyword, then
 
        1) newcomers won't know about it
        2) people will eventually forget
 
and we'll be back to where we started.
 
The way you would eliminate non-tech articles with the new group in
place would be to not read comp.sys.atari.st (general), but only
read comp.sys.atari.st.tech.
