[comp.sys.mac.hardware] Software Diagnostic to Repeat Mac Self-Test

sksircar@shade.Princeton.EDU (Subrata Sircar) (04/14/91)

I apologize in advance for cross-posting to three groups, but I'm not really
sure where this belongs.

My roommate's Macintosh has an occasional power-on problem in that after the
keyboard switch is pressed, it will play a sound like "da-da-da dum" and sit
there, repeating the sound if the debugger switch is pressed.  It never lights
up the screen.  The problem is intermittent, so I gather that the Mac IIci is
failing its internal self-test.  It's an 8M Mac IIci running 6.0.7 with an
80M hard drive.  I've run numerous tests on the hard drive, and it seems to be
fine.  The problem predates both the addition of the extra memory and the
upgrade to 6.0.7.

What I'm looking for is a software program to run the internal self-test, or
a program to tell me which error the sound corresponds to (a program called
Diagnostic Sound Sampler was mentioned in the last MacUser.  I looked through
the archives on ux1.cso.uiuc.edu for the User's Group disks, and couldn't find
it.  Is it available for anonymous ftp, or could some kind soul mail it to me?)
or some probable sources of error.  Is it the SIMMS, the ROM, or what? and how
can I fix it?  Even advice like "Take it to your dealer and let him worry about
it" will not be ignored.  Thanks in advance.

Please email to me, as 1) I doubt this is of general interest, and 2) I don't
read all of these newsgroups so I probably won't see your post.
