If this is a true story, wow. Without any confirmation, he just shows up with a suitcase? That's quite a lot of effort without first confirming the transaction — good thing it worked out.
The guy used the software to found DMR, one of the largest IPSPs of the time. Afterwards they contracted me for 3 months to modify the system to their liking, so I got to visit Minot in the middle of the winter, to work together with their programmers. Interesting times.
Turns out he knew me indirectly because another customer of mine was a friend of his, but I didn't know that at the time, to me he was a stranger.
