You shouldn't rely on getting a bus error (or not getting one) anywhere.
People can muck with the variables you mention, so you really can't
count on them.
This is a good time to publish my universal bus-error code fragment. It
works on any CPU and it doesn't even have to check what CPU it's on. Of
course, it must run in Supervisor mode, because it fools with the bus
error vector. The key to the code is that it cleans off the bus error
exception from the stack regardless of how much the CPU put there. It
does this by saving the original SSP and restoring it later, rather
than adding a constant number of bytes to SSP. (If you DON'T get a bus
error, the final "move a1,sp" is a no-op.)
begin:
move.l $8,a0
move.l sp,a1
move.l #berr,$8
* Do something that might cause bus error
move.l testaddr,d0
* If you get to the next instruction, you DIDN'T get a bus error.
* Handle that case here (zero a flag), then branch to berrdone.
sf berrflag
bra berrdone
* If you get to this label, you DID get a bus error. Handle that
* case (set a flag), then fall through to berrdone.
berr: st berrflag
berrdone:
move.l a0,$8
move.l a1,sp

Are you talking about standard Gribnif or Royal Gribnif ?
There are significant differences, you know.

Thanks for the updated format list Ian.

Message-ID: <9004110307.AA28181@lash.utcs.utoronto.ca>
A friend of mine is moving to France from Toronto and is worried
about problems that he may have with his ST. He has a step-down transformer
to get to 120 V, but can't do anything about the difference in frequency.
I expect that there won't be a problem for the computer itself, since it
rectifies everything to DC anyway, but what about the colour and monochrome
monitors, and the hard disk drive (sorry, I didn't think to ask the make).
He also has Spectre 128 and the Translator. Are there any other problems he
should be aware of, such as incompatibility of European software on North
American machines?
Any info would be greatly appreciated. You can mail to me directly or
post to the net, since I read the Bitnet compilations regularly.

Hello,
I got a letter from 'Heim-Verlag', the german distributor of PC-Speed.
They told me, that a 80286 Version will be available in June. The did
not tell anything more.

Well, let's see if I can remember back that far...I think this is how I did it:
First, format drive C and set it to autoboot with the ICD software. If it is
already set to autoboot, then copy all files off of the drive because you are
about to erase everything.
Second, boot up pcditto and issue the command FORMAT C: /S
This will logically format the disk and write the system and boot sectors onto
the partition sector (0). When finished do the <CTL><ALT><DEL> thing and go
back to the title screen. Reboot the IBM mode from the hard drive this time to
see if that works at least. When you have the IBM system booting off the hard
drive then go back to ST mode.
Finally copy your ICDBOOT.SYS back to drive C and now boot the ST to make sure
that works. Then run pcditto again and make sure that works. If I remember
correctly, that is how I did it and it works on my system.
Once you can boot off both systems then you can put all your files back on drive
C and continue as normal.
Oh, one thing...You cannot have a disk in drive A: when booting from the hard
drive in IBM mode, the program will lock up. However, after the boot cycle is
over, it is wise to put a disk in drive A: and access it, otherwise the motor
will keep running (my drive light is not on, but the motor is running, this
shuts it off).

Subject: PC rag notices the TT
Message-ID: <9004110333.AA29102@lash.utcs.utoronto.ca>
Having to deal with mserable-dos machines at work, I try to keep up
with the field be reading a few pc publications. One of them, PC WEEK, is a
weekly tabloid-style rag with lots of product anouncements and
advertisments that they will send you free if you can convince them that
you are responsible for buying lots of hardware or software for your
company. (It's actually quite useful, and they are frequently very
critical of IBM, which matches my opinion nicely.) One of the must-read
columns is called Rumor Central, by "Spencer F. Katt", on the second last
page. In the issue of March 26, 1990, he describes his trip to Taiwan to
see what Intel is up to with the 586 processor, then continues:
"Of course, the Katt didn't return straight home from the land of
Chiang Kai-shek. He hopped Lufthansa to Germany for the Hannover Computer
Fair, and feasted his eyes on goodies being shown there, including a new
Atari machine -- which runs Unix on a 68030 processor and will sell for
less than $2000."
This reference to the TT is the only thing he says about the
Hannover show. True, this wasn't a front page article, but maybe things
aren't beyond hope for Atari if they can get some attention in a
publication that describes itself as "THE NATIONAL NEWSPAPER OF CORPORATE
MICROCOMPUTING". (Being a Canadian, I will give them the benefit of the
doubt and assume that by _national_, they mean _not-regional_, and don't
mean U.S.A.)
I just thought there might be some interest.

Perhaps it's been munged. I'll upload it again; look for play2.arc.

The standard way to handle this kind of thing is to make a mailing list...
I'm not exactly sure, but I think that just means setting up a mail alias
and sending the stuff to the alias. Or you might set up a group in the alt
hierarchy: alt.pictures.spectrum, perhaps. Of course, even some people who
wanted them might find an alt group hard to get.
