Hi':'
'
On one of our two machines we can consistently get 513 in the following'
manner (I have delayed this long in responding to your offer,'
since I first had hardware folks '
come out, since my high level heuristic is that if only one machine'
running the same software fails, the problem is hardware. The hardware'
people say no, and talked to someone (Marty Raime?) in Pasa.'
who said it was software, so...).'
'
The high-level goal is to copy a floppy, say one of the lisp-library'
disks. to do this I load all the files on to the hard disk and then'
load them back down to a second floppy.'
'
................................................................'
'
I then edit COPYTODSK to make it a prog, ie.  '
'
  (PROG NIL (PROG NIL (COPYFILE (QUOTE {FLOPPY}FILE1.;1)'
				(QUOTE {DSK}FILE1.;1))	'
		      (PRINT 1))'
	    (PROG NIL (COPYFILE (QUOTE {FLOPPY}FILE2.;1)'
				       (QUOTE {DSK}FILE2.;1))'
		      (PRINT 2))'
     etc.'
'
(EVAL COPYTODSK)'
'
and flashing 513 sometimes. I cannot get it to break after any'
particular file, sometimes it stops after printing 4 or 11 or even makes it'
all the way through.'
'
If this succeeds, I remove the source disk put in the destination disk and'
I then make a prog to go back to another floppy using the same'
steps, getting something that looks like':'
'
  (PROG NIL (PROG NIL (COPYFILE (QUOTE {DSK}FILE1.;1)'
				(QUOTE {FLOPPY}FILE1.;1))	'
		      (PRINT 1))'
	    (PROG NIL (COPYFILE (QUOTE {DSK}FILE2.;1)'
				(QUOTE {FLOPPY}FILE2.;1))'
		      (PRINT 2))'
     etc.'
'
this prog succeeds 1 in 20 times, which I consider repeatable,'
though it doesn''t freeze after the same file.'
'
Summary':'
======='
'
1) When I copy a large number of files from floppy to hard disk I get'
   flashing 513 some substantial % of the time (30-40).'
'
2) When I copy a large number of files from hard disk to floppy I almost'
   always get flashing 513.'
'
3) This only happens on one machine, which has had its floppy drive'
   replaced and its CP(?) board swapped without making any difference.'
'
These progs succeed in copying files on our other 1108. I hope this'
is helpful. I am sorry this is so baroque, but I really haven''t'
thought hard on how to call the editor from a function and do the'
editor steps I now do by hand.'

thanks.'

     ATTN should be 1100SUPPORT or RAIM.  There is nothing I can do'
about this problem that I am not able to reproduce on any machine'
here at PARC.  I''ve sent at least 3 messages to 1100SUPPORT detailing'
my recommendations on how XSIS should handle the situation and/or'
asking that XSIS give this user a response of some kind.  THERE HAS'
BEEN NO ACTION ON THIS PROBLEM, AND THERE WILL BE NO ACTION ON THIS'
PROBLEM UNTIL 1100SUPPORT ACTS DIRECTLY WITH THE CUSTOMER OR GIVES'
ME INSTRUCTIONS TO TAKE ACTION WITH THIS CUSTOMER.'
