[comp.sys.ibm.pc.hardware] RA70 drive in an AT?

acyoung@rodan.acs.syr.edu (Aaron C. Young) (05/30/91)

	What kinda of drive is an RA70?  Can I put it in an AT with a
	standard controller?  

	Any replies would be appreciated,

My experiences with an RA70 is that it is a Dec DSA drive of ?? meg
(200 or so sticks in my mind).  Ah, it would be a bit difficult to
hook up to an AT.  You'd have to get some controller which would hook
up to a DSA disk and give you some type of reasonable output, maybe
SCSI or IDE.  I'd bet the SCSI might be available but it could be
expensive.  For that size disk you probably can get a good pc disk of
the same size and speed for less money.

Sorry.  The RA70 is a DEC drive which uses their DSSI (or is it SDI?)
interface.  This is not compatible with any standard interface card.
Your best bet would be to find someone (like a used DEC dealer) who 
would accept it in trade for a drive that could be connected to a PC,
such as an RD53 (70Mb MFM), RD54 (190Mb MFM) or one of the RZ series
(SCSI).
