[comp.sys.dec] Ditch 11/750, save RA81's?

brian@hfh.edu (Brian A. Wolfe) (10/09/89)

Hi There,

I'm hoping to get rid of an 11/750 sometime in the next few months
and I was wondering if its possible to salvage 2 RA81's (and an RA80)
for use with a Microvax 3500. Does a Q-bus controller exist for these
monsters (and is it worth it?).

Anybody know if there'd be a way to use these disks on a Decstation 3100
or Sun Workstation? 

Thanks in advance,

Brian.

	Don't know about the RA80 (those were in use before I was born
(okay, maybe a slight exaggeration)) but the RA81's are definately 
usable.

	Yes indeedy, its called a KDA-50.  Supports 4 RA style disks
(ra70's, ra81's, ra82's, ra90's).  Its a two board set.  Don't know
how to answer the other part.

	Don't know about the Sun (I think its scsi).  Not directly, you would
either have to run VMS on the 3500 and then get somebody's tcp/ip implementation that
has NFS or run ultrix and then NFS to your DECStation 3100.

Yes, save the RA81s AND the RA80. It runs off the same controller as the 
RA81s. You can't have too much disk space. You should have your 
maintanenance outfit check the ECO level of the drives. The RA disks have 
gone through quite a few changes, some actually for the better!
