Hi,

     I need help, I have a MacIIcx 8megs ram with internal 80 meg HD and
I am running System 6.07 as I am doing some work with HyperCard 2.v2, and
I have a serious problem with it crashing. Attached to the CPU I have an 
external SyQuest drive which I love and need for backups and storage of 
little used files, an exteranl 60 meg HD with a Segate ST277N-1 mechanism,
a standard Apple ColorCard and 13" Color montitor, and Teleport modem.
I get a series of different error messages most of which are bus errors  
(see list below). I have the problem when either one or both of the drives 
are attached or it I attach any other HD (I have tried 6 different). To 
confuse the issue even more I have this problem with all of the drives
if the devices are terminated following Apples rules. If any device or 
combination of devices are attached and left without termination on any 
device everything works great. I use this computer for work, so I have 
Apple Care on it, and I got the mother board and hard disk replaced. 
Neither of which cured the problem they only gave me more frustration. 
I can work with the system unterminated, but what happens when I add a 
new 
SCSI device of that requires termination. 

Can anyone out there HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
