As the author, I may have been the only one.

What a story. The bubble memory module was discontinued by the 
company (Intel was it?) after the article went to print.

Here's how it went: We had samples from the company, designed and 
built the unit, had the boards made, and had a finished and tested 
unit. I think it went to Jake Commander, who had been writing a 
Bubble OS for it that would have appeared in a later magazine. We 
were negotiating a price on these bubble memories (they were really 
expensive and required weird powering, too) and one Monday morning we 
called to place our order. The number was disconnected. The entire 
company division had been shut down over the weekend, and bubble 
memory manufacturing was ended.

So as far as I know, my unit was the only one built -- unless other 
people had access to the discontinued bubble memory modules. We sold 
one circuit board, as I recall, and eventually refunded the purchase. 
We sold our small sample kits of bubbles and controller chips to an 
interested person some months later.

And here's a coincidence -- yesterday at 3:00pm all that material 
went to the dump!
