George:

The DEC HD controller will handle drives of much larger capacity, I have an
ST-251 40 MB drive on mine and know of others with even larger drives.

The problem to over come is the DEC Winchester Utility, I think only
handles upto 20mb drive.

There is a PD utility avail on many RB BBS called WUTIL that will format
and partition large drives.

You will also have to modify the boot loaders if the drive you select has a
different number of surfaces than DEC bootloder supports(I forget the
details)

A PD program POLYPRAT does this.
