I used to live a couple of miles from the North Fort Worth outlet store (closed about 3 years ago).
They had tent sales and sold some strange stuff. One thing was a holdover from the original PC period, a full length ISA card that would back up the hard drive to a VHS tape, but with no software to make it work (if it ever did work).
I loved to bargain hunt in the outlet section and those occasional tent sales.
I remember that technology. . . it worked. However, there was a limit on the size of the hard drive that was not that huge. And restoring was finicky, if I recall correctly.
