Hi Mark,

Good to know...and thanks for the V5 vs. V6 tidbit.

Found something on the Interweb from "Clark's Blog" about resurrecting the
VAXen
https://blog.deadvax.net/2015/10/01/scsi2sd-part-2-of-resurrecting-the-vaxen/

is the following link for "*The SCSI Hard Drive Emulator for retro
computing."*
http://www.codesrc.com/mediawiki/index.php?title=SCSI2SD

Will look into this more very soon, as one of the old hard drives
periodically whines a bit.

Thanks again,
Jason
