Subject: 3b.*

I have just heard from Peter Yee at ames and he gives me the
go ahead to say that ames will be glad to pass on the newsgroups
to existing feeds. Which means that it will basically be all over
the nntp world.

Looks like connectivity won't be that bad.

Again, if you need a 3b.* feed, just contact me. I will also
be contacting Mel Pleasant at rutgers.edu today.

 I am currently trying to come up with a valid way to test
 the 10 mhz box vs the 14 mhz box. Locally I have one 310
 w/o mau and a 400 w/mau.. I use two different compilers.
 I can't believe this will facilitate something accurate so
 I am going to enlist a few people in the comparison. 

 If you would like to get involved in this, we may be able to
 come up with a more accurate picture.

 In a few days time when things stabilize with this newsgroup,
 I will post the dhrystone sources that we should all use.

 (We will wait awhile before creating 3b.sources) smile.

 I will post them here I suppose.

"All of us who upgraded from 3B2/400s to 3b2/500s or 3b2/600s
 know how much nicer/better/faster the built-in 60MB SCSI 
 cartridge tape drive is over the 23MB floppy-drive-emulating tape thing
 used in the 400."

 Will the 60 MB scsi tape drive fit in the same physical location as
 the older 23 mb drive. I.E. If I buy a scsi tape can I install it 
 in place of the old drive.

"While I'm on the subject of comparing SCSI devices for the 3B2,
 AT&T sells both native SCSI hard disks and ESDI hard disks that
 need a SCSI-to-ESDI thing like the ones that come with the
 3B2/600. Does anybody have experience with both types?"

  Whose drives does AT&T use.. CDC or?

  Has anyone been successful in using other brands of drives than the
  one supplied by AT&T for the SCSI XM packages.. I understand that
  if you want to use ESDI drives with the SCSI controller you have to
  use some sort of bridging adapter. We have some Micropolis 1355's
  (170 mb) that we would like to use and I am wondering if they can be
  made to work with the AT&T scsi interface. Is the bridging adapter
  (for scsi to esdi) available seperately?
