@carls (and apologies for going even further offtopic)
There was some other company making "luggable" A4000 machines.
Hmm, never saw such a thing at the time. After the SP thing fell through I was looking into using shock-mounted racks (like some musicians use for their rack-mount effects and such). Couldn't find a rack-mount case for the A4000, though there was one produced for the A2000. Considered moving the Toaster/Flyer to my A2000, but would have needed an accellerator, which I'd just bought for the A4000...
Then the flood of '97 came to Grand Forks, ND, and I ended up relocating to Fargo/Moorhead, and my Toaster/Flyer is still a desktop thing.
