[comp.sys.amiga.hardware] HELP! I've got sick Amigas!

My brother has an Amiga 500 (purchased 11/89) that went wacky yesterday.  He
said he used it that morning but by night it wasn't working.  It seems that no
matter what disk he starts with he gets a "disk not validated" or "disk
structure corrupt" message and then usually read/write errors on the disk.  The
first time this happened on a game disk that had never been un-writeprotected.
He says occasionally a green screen appears at boot, but it doesn't happen all
the time and always continues booting (until the disk errors).  Could bad ram
cause disk problems? or is it the disk controller?  It's got me stumped, any
one ever had a similar problem.

Now, on to my sick amiga.  It's a 1000 (bought early '86, still own KS/WB 1.0!)
I have a minimegs 512K expansion and external floppy.  The problem is this, 
after a variable length of time I will get a "software error" message and a 
Guru with the number 0000000B or 00000003.  I know 03 is an address error and
0B is Op Code 1111. What I don't know is what could be causing this and what 
an Op Code 1111 means.  I suspect the power in our apartment, but my roomate
has a 1000 also and has not had this problem.

Thanks.

BTW anybody know anyone looking for an alto sax?  I'm selling mine so I can
get a 2000!

About the sick A1000 -- I can say ours did that until
we built our bus terminator. I highly recommend this
fix to anyone with a A1000 with add-ons.
