Subject: BA23 w/RA70
Well I've got this empty BA23 and enough boards to
put
together a MVIII/kda50. What I don't have is the RA control
panel.
My question is, can the RA70 be set up to run without it?
If so, what jumper/sw settings?
The box may be an earlier model, badged microPDP11, so
I have to wonder if the VAX, 2 mem bds, kda50, RA70,
RQDX3 (for the RX33) and a DELQA would be too much for
the P/S.

Actually, this is a long-held question of mine too :) I've got a MicroVAX
III
in my basement in a BA123 with four RA72 SDI drives and a KDA50
controller. Unfortunately, I didn't get any cables for connecting the card
to
the drive when I purchased the card, and I really don't know much at all
about the SDI disk interface in the first place.
Just out of curiousity, does anyone out there have a pointer to a site that
has
a good file explaining SDI, or would anyone be willing to explain the
basics?
Do I need anything else besides the card and the drive (like this RA-series
control panel mentioned in the previous message)? How are the drives
cabled to the card? Is the cabling something relatively straightforward that
I could put together myself?
I think it would be cool to get the system running with them; they've been
just kind of sitting in the basement as a "to-do" project someday.
Thanks,
