666.0. "Help - bus errors!" by PDP10::BHAMILTON (Buzz Hamilton) Sun Nov 12 1989 12:19

    Can anyone give me clues as to what might be happening with my system?
    
    I have an older 520 (no composite output, external disk) with a half
    meg upgrade via EZram II. I just recently acquired an SH204 hard drive.
    I recently upgraded to TOS 1.4.
    
    The PD STETRIS2 program seemed to work OK previously. Yesterday, I got
    a rash of bus and address errors. STRETIS2 seemed to consistently cause
    bus errors shortly after starting. Switching back to the old TOS 1.0
    ROMs cleared the problem. Since STETRIS2 worked previously under 1.4
    I'm not convinced it's a compatibility problem. The old ROM set was six
    chips, so I shouldn't be overloading things as when you are upgrading
    from a two-chip set to six.
    
    I'll try running STETRIS2 from floppy with no HD and see what happens.

    Well, that made a big difference. No hard drive - No problem.
    
    Is this another manifestation of 'weak' 74LS373 bus driver chips?
    
666.2"Indy and the HD of doom" :-)OLDTMR::WALLACEMon Nov 13 1989 11:196
Is having the HD attached what is causing Indy not to work as well?

With the HD attached were you running STETRIS2 from floppy or from the HD.
Maybe you have a bad copy of STETRIS2 on the HD.

666.3AHDI V1.7 ?EIGER::BOLLIGERWed Nov 15 1989 05:459
    		( ATARI HD INTERFACE -->AHDI )
    
    YOU SHOULD TRY IT WITH AHDI VERSION 1.7 , INSTALL VERSION 2.0
    NEWER VERSION'S LIKE 3.0 OR 3.1 ARE NOT WORKING WITH ALL PROGRAMS
    
    PS: AHDI.PRG  OR INSTALL ARE ON THE HD BOOT-DISK

    re 659.7
    
    Yes, my problems described in the base note seem to be related directly
    the the NEODESK V2.0 printer queue accessory and TOS 1.4.
    
    I held off entering an update to this note until I had done some more
    exhaustive research.
    
    GRIBNIF has rewritten the Printer Queue Accessory, I believe. They are
    scheduled to be at the November NaVaus club meeting. I will be getting
    an upgrade to the latest level of NEODESK at that meeting and we will
    discuss the problem with Rick Flashman.
    
    STETRIS2 did not bomb in a consistent fashion with 1.4/NEOQUEUE but did
    fail. It does not fail when NEOQUEUE is not installed.
    
    Sorry for the faulty alarm on 1.4.

    That doesn't surprise me, I've seen the same thing.

>GRIBNIF has rewritten the Printer Queue Accessory, I believe.

    I hope so!

>STETRIS2 did not bomb in a consistent fashion with 1.4/NEOQUEUE but did

    When I tried out my latest version of GFA Basic, version 3.07, it
    crashed EVERY time I tried to start it up, due, I think, to a bus error.
    When I deinstalled NEOQUEUE, GFA Basic never crashed. Other software
    also seemed to suffer sporadic hangups/crashes, but they all went away
    when I removed NEOQUEUE, so I now avoid it like the plague. NEODESK,
    itself, however, is great!

    I posted these two atricles the other night while I was look-
    ing in comp.sys.atari.st.tech for 'bus errors'.  My 1040ST
    just started doing this this past "weekend" sometime.

	I've got a TOS 1.0 1Meg 1040ST with 65M h/d that has been
working fine - 'til I tried to do a direct (hardwire - no modem)
xfr between it and another system.  Normally, this works at 9600
with no problem.  Today, I started seeing 'bus error'.  Tried
2400 - same thing.
 
Over the weekend, I did run TOS14FIX (the rainbow TOS fix) to see
what it'd do - I wanted to 'play' with the 19200 baud and thought
I might need it.  I can't see that effecting it, 'specially with
rebooting the system, but thought I'd mention that too.
 
					Any ideas?

    That last part about working fine with the modem attached - I found
    out last night it's not true.  If I disconnect my Hard disk (Seagate
    277N w/ BMS200 controller) everything works fine to floppys. 
    
    I can boot the HD, open files, create them, run mint, Gulam, ue new
    files - just can't get CKermit to work anynmore (it has been for
    the past 6 mos. easy).  Any ideas on how to isolate this further?
    
    Is this a bus "driver" problem?  Need moor info?
    
    					Thoughts appreciated,

Hey, same thing happened to me last weekend (MEGA 1, some kind of
global infection? :-), when I tried to use ckermit to fetch a file
from another system. Using the file transfer capabilities of UNITERM
_did_ work. 

I had no time to look further into it, but if I recall correctly, the
last time ckermit used to work was before I attached a second hard
disk to my OMTI controller. Hmmmm, I'll try to disconnect the hard
disks and check it out. When time allows. 

rdgs,

666.8WHACK works...DETOO::HEARNTime will tell...Thu Dec 05 1991 07:267
    
    peter,
    	    one thing I did find out - with Ckermit.tos it appears to
    	bomb with the file create to the hard disk.  It doesn't happen
    	if I use Jeff Lomicka's WHACK.PRG - that ** Successfully ** 
    	works (jeff, how'd you do that? :^)
