Music, hello and welcome to this review of my Leading Edge 88-15K. I've been looking forward to showing you one of these for a long time as it uses a top-of-the-line switch that's extremely rare and unusual. The only other example I know of is an NCR keyboard that Ex Mitt restored a long time ago. But then this Leading Edge model showed up on Desk Authority, new old stock even, and I offered to buy it.

It was subsequently acquired by Daewoo as early as 1989, despite the huge success of the Model D computer. That said, the 88-15K itself, or actually the Model M keyboard as it should be known, is much more of an enigma. I can't...
