Help!   =-)
I need to acquire a Northstar boot disk (CP/M) for a Horizon with an
MDS-AD3 controller.  It's also got a Disk Jockey IID/B.  I have all the
documentation for the machine just no boot disks.
BTW, this is not the crusty one mentioned on 
http://www.retrocomputing.com.
It's another one I purchased complete.  Although, having a working one as
a template gives me better feelings about trying to resurrect the crusty
Northstar.  We'll see.
