20 Bombs!!!
ten...@mail.com
number of bombs you get denotes what sort of error it is, but I have long
forgotten! It happens to me when I use Pacifist to play Championship
Cricket from the Automation CD11 (or rather the disk image of it), and I go
to play a County Championship game. Anyone else expirenced this and is
there anyone who knows how to solve it?
Thanks

You've 'bombed out' big time.
It sounds like a multiple error, when an error occurs during the
handling of another error, upon another error...

Unless you are a programmer familiar with 68K assembler, then I doubt
the number of bombs will tell you much anyway.

Run an original copy on a real ST ?
This sort of thing happens on emulators. People just expect them to run
just like the real thing, but the fact is that no emulator will ever be
100% compatible with the original machines, especially when the various
varieties of original machines weren't 100% compatible with each other
anyway.
Just try another TOS version/RAM setting/video mode, etc... Some other
things won't run whatever you do.

was an issue of the ST Format Magazine that told you but maybe I just
imagined it! A multiple error sounds most likely though. But I'll try
running Championship Cricket on my 1040 STFM to see what happens but I don't
have a real copy - I think if I use pcdrive I will be able to copy it over.
I know what you mean about the emulators though I don't expect it to be
perfect becasue after all its only on a PC!
Thanks for the advice though.

: Does anyone know what having 20 bombs across the screen means?
No, nobody can answer that question. Bomb numbers 16-23 are unassigned.
The most common numbers are basic error numbers, 2 for bus error, 3 for
address error, 4 for illegal instruction, and 5 for zero divide, all
meaning that something got confused.
I have looked this up so many times that I finally wrote it in the Error
Codes section of my Compendium, where it belongs.
It has been four years since the 12/93 version of the FAC was last posted.
That is my mother lode of such information.

You are right, the bombs do have a meaning. IIRC multiply the number of
the bombs on screen by 4 gives you the exception that caused the
problem.
The only problem is by the sound of it you have had more than one lot of
bombs, or more than one exception error. This means during execution of
the error, whether it be address, bus... another exception happened and
another etc.
For a guess the 20 bombs went from one side of the screen to the other!
So it's safe to say that if the screen had a larger resolution (more
dots on the screen) the bombs would have kept on going until the machine
hangs up.

I thought they went to the next line?

They do but there aren't any errors defined for this many. It'll be a
case of multiple crashes. Basically the system has been scribbled on
so bad it can't even recover after issuing the initial amount of bombs
so it promptly bombs again. After a while it'll get so bad the
processor will usually halt itself.

Ah, if the game runs okay on a real machine (or even just bombs more
"reasonably") it is likely you've encountered an inconsistency in the
emulator. Good be worth a bug report?
Maurits van de Kamp
write about them.. it supposedly means TOS detects an error that could
"damage the operating system" (it still says so in the Mega STe manual
which, IIRC, never had a disk-based TOS) :) The advice (please ignore
this) is, if a program bombs, immediately switch off the computer "to
protect the operating system" (lol!) and if it happens again, never use
the program again. :)
I wonder how much damage I'd do to my operating system if I'd switch off
my falcon immediately if one of my 30 processes under MiNT produces a
buserror. I think I'd rather just continue working, thank you very much.
:)
Just to prevent misunderstandings, the bombs are nothing more than a
result of 680x0 TRAPs that are not used for anything else, ie the 680x0
error TRAPs (bus error 2 bombs, address error 3 bombs, devision by zero
11 bombs, stuff like that). I don't think there is any error that can
cause a trap 20 (if my memory serves me right that is) so 20 bombs
should indeed be a combination of errors. Pity Atari didn't remember to
add a space behind the last bomb. :)

Even that won't help, as vector 20 is undefined by both Atari and Motorola.
The only way to get that exception is by a program that changes the base
vector register of some hardware chip and then triggers that interrupt,
which is not the normal way of using any of the standard chips.
Under the circumstances I rather suspect some emulation error.

the pre-ship code just rebooted the machine without warning; i added
the bomb icon scribbler so that at least you knew that *something* bad
had happened. i'd wanted to do a "sad mac" like dialog, but there
just wasn't any time
it's theoretically possible to get up to 255 bombs, if things get
really messed up in the interrupt vector table

So then I take it you worked for Atari ? :-)
What was your position and was it a nice environment to work in?
Do you still use Atari's?

I can't believe it.. I'm talking to the person who actually MADE the
famous Atari bombs, prolly the most successful Atari program ever which
has even made it to various Linux screensavers? :)))
Well the sad mac is certainly funny but I must say I'm glad you came up
with something original. :)
