Re: Using 20SC with //GS?

Wayne;

Say, your in BC ! I am in Parksville on Vancouver Island. I'm
surprised by the number of people from BC I've been running into in
the Apple arena.

The reason for the 2.1 gig drives is that I already have them. I also
have some cabling etc from a RAID array that I can use.

My understanding is that when my //gs arrives I'm going to go through
some hassle with xfering the Apple progs from the PC ---> Apple. After
that, I anticpate a hassle decompressing all this stuff. My plan was
to xfer it over, decompress it, organize it and than use it/archive
it.

Because of the time involved in doing this, I wanted to lay it out in
a neat manner and back it up onto another drive. CD would be
prefferable, but I can't see a way of doing this without making the
disk unreadable to the //gs. (that I'm aware of)

So I guess it comes back to keeping the progs 'internal' to the //gs
or having them external but in the //gs native format. How to
accomplish this - I don't know. I don't even have my //gs yet and I've
already got more parts & periphs coming that I can keep track of!

Back to the scsi card topic though.... I did see that there are
different Apple scsi cards out there. The prime difference seems to be
revision number. I have an opportunity to pick one up from Greg
Buchner but I want to ensure I get the right one (read fastest and
most compatible). Also, there seems to be issues with termination
power on the Apple card (some support it - some don't)

What to do? What to do? Anyway, hope it's not raining over there......

Best;
Marvin
