[comp.sys.mac] Sad Mac -- HELP! Replies

hunt@cg-d.UUCP (03/20/87)

********************************* REPLIES *****************************
As promised, here are replies to my question about the Sad Mac error
and my disk problem.  I have taken Mr. Mac+ in for a look, and there
was a real disk problem :-(.  It appears from some of the responses
that I wasn't very clear -- there's nothing wrong with the switch,
it works fine -- it's a problem with the drive itself.  

In any case, thanks a lot for your helpful comments and replies.  I'm
pleasantly surprised by the quick response to my request for help.

I had very similar problem. It turns out my internal disk drive broke
(after about 5 month). The drive had to be replaced ($220 at local dealer).
I've seen many messages on the net that 800k drives are not very reliable.

	Fear not!  The Sad Mac icon that you got merely means you
pushed the interrupt button on the programmer's switch.  Nothing is broken,
except maybe the system on one of your disks.

	The reason that you get a Sad Mac is that when the computer
has no operating system the debugger (either the minidebugger which is
present in ROM on the Mac+, or MacsBug, &c.)  Is not yet hooked in so
that when you push the button requesting a debugger there is nothing
to do but signal an error.

Sometimes the paramters stored in the battery-backed-up parameter ram can
keep a mac from booting. The fix is simple and harmless:
1.) Unplug the Mac from the wall.
2.) remove the battery in the upper back of the macintosh.
3.) wait thirty seconds
4.) replace the battery (make sure you get it right way up - the case is
marked with the orientation.

You'll have to reset the date and time after doing this, but as an IBM
sufferer you'll be used to that. (Use Apple's Alarm Clock desk accessory
to set the date and time.)

Good luck.

The 0F prefix on the error number indicates that it is a hardware failure in
the floppy disk drive.  The last four digits I don't know about because they
changed for the Mac plus and I haven't gotten copies of the new ones.  Sorry
to be the bearer of bad tidings but repair should be simple since the only
option is to replace the drive.

The reason you get the sad mac at startup is most likeley because your
Programmer's Switch is stuck. Take a screwdriver and
gently lift the back switch, so that it pops out. A Tip:

when you get a sad Mac, look at the number under neath. A number
beginning with 0F00 indicates a system error, and the last two digits
are the system error number in Hexadecimal. In this case, 0F000D
measn that system error #13 occurred. System EArror 13 is the
error that's posted when you hit the back button on
the Programmers Switch, hence my guess that it's stuck.

Your other problem: It's possible that you have a corrupted
System or Finder file; mostlikely the Finder, so try replacing it and see if it helps.

Hope some of this information is useful to you...

The sad Mac code 0F000D is the error that occurs when the interrupt button
is stuck in.  Try pulling the switch level out a bit and rebooting again.
Good luck,

In the Dr. Dobs Journal article that I used to upgrade my mac 128k to
512k, it says that the 0F000D means 'normal operation', ie. everything
is OK. You should only get this when you HOLD the interupt switch down
during power-on, so my first guess would be that the interrupt switch
may be shorting out or stuck or something.  If you have ever done any
hardware work, you should have no trouble ding this sort of thing.  If
not, you might want to take it to a dealer, although you're right, their
prices are out of this world.  My 's' key stopped working once, and they
wanted $50 to look at it, plus parts and labor over 1/2 hour.  I fixed
it myself in about 20 minutes with no new parts, and I'm no hardware
person. Anyway, I'm rambling.  Oh, another thing you might try is
booting from a different disk drive (external) to check out your drive,
and if that works you might check the ribbon cable from the mother board
to the internal drive -- mine came loose once and so did a friend's.
If you want to take the cover off, there are 5 screws -- 2 in the
handle, 2 plainly visible in the back, and one in the battery
compartment.  Good luck.

This means the mac is hungry and needs to eat.

Seriously, though, you will probably get a million replies, but just
in case:

   F00D means that the NMI interrupt button is pressed.

There seems to be a problem with these buttons on the MAC+ that they
tend to get stuck.  If you remove the plastic button from the case it
will probably be fine.  Others may tell you how to 'fix' the button, i
don't have a mac+.  IF the button is NOT stuck, then the switch itself
is probably faulty (very cheap critters).


				hope this helps,
