Greetings --
After returning from the Expo in SF, and after catching up with the
volumes of news articles in net.sources.mac, I have a few comments
which may be of interest to you:
Re: Reed College Maturity Discussion
------------------------------------
I don't have too much to say about this -- just a note of thanks
to those who posted articles in support of the materials that have
come out of this lab, and/or in support of source posting in general.
Also, as someone pointed out, it is from this login (maclab) and not
from hundreds of faceless Reed students, that most of the postings
in question originated from. Let's not continue this trend of
maligning an institution for the actions of individuals.
Re: Billiard Parlour Crash on HyperDrive 20's
---------------------------------------------
Again, my apologies for those of you who had Hyperdrive crashes
because of Billiard Parlour (posted under the name 'Collision
Dynamics Application'). I finally talked to Jay Roth from General
Computer and found out what is going on.
The Problem: As most of you know, the HyperDrive 20 system includes
their own 32-bit custom trap manager (they had to write it
in order to be able to expand the system heap, thereby
allowing more drawers to be open at any one time). There is
a bug in one of the calls (gettrapaddress or settrapaddress,
I can't remember which): register A2 is not restored after the
call, so any code which calls the bad routine may have
trouble. Apparently, the Free-Form sound mode (which Billiard
Parlour uses) of the standard Macintosh sound driver is
affected by this bug, and hence the crash. So, not only
Billiard Parlour, but also some other programs which use
free-form sound, may have trouble with Hyperdrive 20's.
The Solution: The next release of HypderDrive system software will
fix the problem (I have verified that that is indeed the case).
So, wait for a few weeks, get the software update, then
run Billiard Parlour, and it will work.
Re: Rascal Release
------------------
The Rascal release will be completely out of my hands as of February 3rd,
which means they should be shipping from Metaresearch later that week.
The February 3rd date is more than a guess -- it is a promise to Metaresearch.
I will post a summary of the contents of the Rascal release to the net
as soon as it starts shipping.
