Ah, just found the magazine. It is named Personal Computer Combat Simulations!, and it is actually a 1994 issue instead of 1993.

The magazine.
And here's the article. The product name is Flight Stand. The company's name is Duggan DeZign, Inc., and it is said they already earned Thrustmaster's endorsement, which would help them selling the HOTAS mount.

The article.
Here's an ad of the HOTAS mount. A good ad, I must say, since it gives pretty clear description to potential buyers on how to use the product.

The ad.
Unfortunately, I just couldn't find the product anywhere, not even on Ebay. Worse, other than the article in the magazine, I just couldn't find any other information about Duggan DeZign's Flight Stand. Did the product fail? Was the company short-lived?
The good side, the HOTAS mount seems like easy to DIY. In fact, according to the magazine article, Duggan DeZign shipped them as flatpacks, knock-down kits to save space. So perhaps you would want to try to DIY one.
Never thought this thread would be that long, but now, for something different.....
