Re: GS Crashing: copying files and Apple hi-speed SCSI (?)

Boy, there is some really good info coming through on this topic.  I just 
realized that this might be good to put in the FAQ.  

Let me summarized what I think I have gleaned from the posts, and then 
have people correct me if I am wrong.

1)  It seems that proper SCSI function depends on 3 things - termination, 
termination power, and magic.

2)  The RamFast provides both termination and termination power.  The 
Apple HS SCSI provides termination, but not termination power.  The 
original Apple SCSI provides neither.

3)  Drives vary in whether they provide termination, termination power, 
and how much magic is necessary to get them to run.

If the above are true, then it would be great to have info in the FAQ on 
how to tell if a drive is terminated and supplying termination power.  I 
can't volunteer to write it because I NEED the info.  If a drive is not 
terminated, that is easy to fix by going out and buying a terminator for 
$10 or so.  But, if it is not supplying termination power, I would like 
to have detailed instructions on how to modify the drive so that it 
does.  That is the situation I am in now.  I have an Apple rev.C SCSI 
that I have been trying to get to work with a 40meg HD.  Adding an 
external terminator on the drive didn't help.  I haven't tried putting a 
terminator between the drive and card yet.  I think termination power is 
my problem.  How do I fix it?  And who would like to write a SCSI section 
for the FAQ? --
