I was under the impression that the internal hard drive on the 1537 is SCSI and not IDE. Careful, some of those pins have +12 power for the drive on them as well. On Wed, Aug 14, 2019 at 8:49 PM Curt Vendel via cctalk < cctalk@classiccmp.org> wrote: > Hi, > > I’m doing some work for a friend

And then there's things that use the same connector, but it's none of the three more common DEC buses! The need that led to the development of this prototype board is actually replacing missing boards in a VT05! Thanks, Jonathan On Thu, Aug 15, 2019 at 10:21 AM Paul Birkel wrote: >
