Well, in 1986, I paid something like $6700 for a KA630-AA
(UVax-II CPU board).
I got an Andromeda disk controller (MFM hard disk + floppy)
and ran pirated VMS off a 40 MB drive. Slowly upgraded it
all to a VaxStation II, then VaxStation II GPX (color
graphics), added a bunch of tape drives.
I kept it running until 2007, when the hard drive croaked.
By that time I had a cast-off SCSI 4 GB drive.
