Lisp stopped itself (still)
(* Thanks to everyone who has helped me with diagnosing this problem.
(* One thing to note is that there's *no* way for me to get into Lisp
(* at all.
(* So far:
(* Scanning and using the tests.flod revealed some sticky bits in
(* one of the 2 MW boards. It went like so:
Test Simple main-memory
Testing memory board in slot 7. = #o7
Testing memory board in slot 8. = #o10
Testing memory board in slot 25 = #o31
At least 1 location has bit 22. stuck on
At least 1 location has bit 32. stuck on
(* and this last statement was repeated for bits 36,37,38,38,40,
2. locations have bit 22 stuck on; addr-ior 63124426, addr-and
6312046, xor(addr-adn, addr-ior) 4000
233. locations have bit 32 stuck on; addr-ior 63120777, addr-and
63120400, xor(addr-and, addr-ior) 377
(* this last statement was repeated for bits 36,37,38,39,40,41,42,
(* all with the same numbers ie. 233. locations...addr-ior #,
(* addr-and #, xor #, including the 377 at the end
Testing memory board in slot 26 = #o32
(* this last statement was repeated for slots 27-30, showed no
(* Then I performed a Test Main-memory
Testing memory board in slot 7.
Testing one location per page.
(* many numbers here, nothing conspicous *)
Testing powers of 2.
(* and this was reported for slot 10,31,32,33,34,35,36 with no
(* errors apparent. Is this testing some board other than the
(* 2 MW boards?
Label for unit 0: 1635 cylinders, 15 heads, 24 pages/track,
Id = 0, Fast mode = 1, Root at 30(8)
Pack name: DE-00355
Testing disk unit 0
Error reading cylinder 1635 head 0 sector 0 on unit 0
Too many retries for unit 0. Last error was: Timed out waiting for
seek to cylinder 1635
(there appears to be 1635 cylinders)
Error while mounting unit 1: Select error on unit 1 during unit
(* This last line was repeated for units 2,3,4,5,6,7 since there's
(* only 1 drive I suppose.
(* It seems that that last cylinder should have been omitted at
(* format time.?
Testing every 177(8) locations: 0 1770 3760 5750 7740
Testing power of 2 locations
(* seems to be no problem here even with the bad mem board in.
(* So from the load microcode report...
Setting up 2MW board in slot 7
Card 1 being assigned to slot 30.
Card 2 being assigned to slot 29.
Card 3 being assigned to slot 28.
Setting up 2MW board in slot 8
Card 1 being assigned to slot 27.
Card 2 being assigned to slot 26.
Card 3 being assigned to slot 25. (* the bad guy!? *)
2 2MW memory boards found
(* I removed the slot 8 2MW board and redid the Simple
(* test main-memory, with no errors then reported.
(* Attempting the boot sequence still comes up with
(* the same error at the "Start" command, so I assume
(* the memory has nothing to do with the disk error.
(* Since I have an IFS tape from the other 3650, I tried to Load
(* Microcode from CART:>3650-fpa-mic.mic but got an error
Load Microcode (default is FEP0:>3650-fpa-mic.mic)cart:>3650-fpa-
(* I knew the file would be on the tape as I was able to read the
(* FEP root on the other 3650 and document its contents...
(* Anyway the error was...
Error while opening cart:>3650-fpa-mic.mic: Data error or bad
block not located
(* Should I assume this means the tape is bad?
(* So I loaded the microcode from the disk, as before, and then
(* tried to load world from this IFS tape.
Load world (default is FEP0:>genera-7-1.load)cart:>genera-7-1.load
Error: Unbelievable (129480788) number of sparse entries
(* I realize this was a shot in the dark...I would probably
(* have to have the tape in perfect position for this...
(* So I went ahead and load worlded genera-7-1-5-combo.load,
(* Enabled IDS, and Started, and I noticed that the first time
(* the error message came up it was DISK-ERROR-ECC instead of
(* DISK-ERROR-SEARCH. The numbers were the same as when I did
(* continue, though it switched back to DISK-ERROR-SEARCH.
(* BTW, what do the <211><211><211> mean?
I assume that the only way out of this disk error is to get an
IFS tape from Symbolics for this machine. Is this tape able to
deal with the bad block (does it create a new base load file)?
Can I get a tape that is compatible with genera 7.1 still?
Geez, that animation I'm planning for next year's SIGGRAPH is
slowly fading away...
I am truly comforted by the helpful responses I have been getting
from you all. If you're ever up in Vancouver B.C. its "hospitality
city" for sure. Anyone want to come up for a visit and fix my 3650s?
:) Free room and board in a nice big house with a view! :)
Thanks again for listening.
