[comp.sys.apple2] DMA SCSI stuffs

swiers@plains.NoDak.edu (Aaron Swiers) (01/08/91)

I have a Woz IIgs, Apple DMA SCSI, Rodime 45M HD, TWGS (latest), and a GS-RAM+
w/4M (latest).  They all seem to work OK a fair amount of the time, but things
do blow up a little more often than I'd like.  Anyway, I've noticed that if 
I keep a 1600K RAMDisk, it very seldom crashes (mostly buggy programs), whereas
with no RAM disk it crashes all the time, usually problems with the hard disk.
So, I'm thinking there's a bad RAM chip in there somewhere.  I went through with
AE's GSRAMTest.System v1.6 says there are no problems, as does AWGS memory test
(I think, I didn't try it again last night).  Anyway, I'm wondering what section
of RAM the DMA SCSI card works with...is the suspect chip in the first bank or
4th bank, or what?  I managed to get this card with no docs or software from my
local Apple dealer (lots of mix-ups, I could have gotten the dox if I wanted to
wait longer) and I don't care to talk with them again.  Any ideas anyone?

Thanks,

Mike
