From article <3302@hermes.ai.mit.edu:, by dzenc@hermes.ai.mit.edu (Daniel Zenchelsky):

: Ok guys, my computer is on the blitz and I need help.  Now, in addition to
: randomly scrambling disk directories (which I think I've eliminated by
: removing GOMF 3.0 from my startup-sequence) my machine (A500) randomly gurus.
: 
: I've noticed that it boots up with a green screen, and I seem to remember
: that that signifies a memory problem.  To test what memory, I took out
: my A501, and 1 Meg Byte Box, and the green screen persisted. So, I ran
: a memory diagnostics program (I got it from comp.binaries.amiga, I think)
: and it didn't find any problems... Hmm...

	Green screen is a pointer to bad chip memory... But remember that
FANG generates CAS* and RAS* for that memory. Normally on a 500 you can
fix the problem by simply re-seating the chip. On the 500 at work, we replaced
the socket with a new Ansley socket. The Ansley had a much nicer clip
arraignment.
 
: Does anybody have a *GOOD* PD/Shareware Memory checker/System Diagnostics
: program?

	I use MD recently to diagnose a problem with an old aMEGA board I
had laying around. It worked well for that application, but probably wouldn't
find most intermittant memory failures. (I wanted to put a buss terminator
on my 1000 and didn't have any other 86 pin female card edges... Now I have
*five* devices on my buss, plus the Processor Accelerator inside!) (Kiddies,
don't try this at home!)
  
: Could it be a loose chip? (Agnus?)
: 
: Any help would be greatly appreciated...
