I believe that was the system that he used... I found an article from an earlier time period with your prompting.

I actually have a stack of multitrack QIC tapes and an old computer still setup with hard drive caddies and a tape backup device in it. I haven't fired it up in years. I would have to replace the CMOS battery and try to remember which settings to use in BIOS to get everything to run correctly... hopefully the defaults would work... and then I could see if that device could still read any of the tapes.
I didn’t want to say Alpha Microsystems was the vendor. Back in the day, they were selling 68000-based systems, running what looked like a TOPS-10 knockoff OS, to system integrators for custom hardware & software solutions.
I wasn’t sure if Alpha Micro had produced a mass-market version of their backup product.
