The first 24 Mhz FX logic analyzer was the (Cypress FX/FX2) reference design made with their development board
The chip manufacturer's reference design basically downloaded its software on the fly into their board.
If we consider that, one can only conclude many manufacturers essentially cloned those boards.
That was the reference design, it was encouraged. So the manufacturer could sell more chips.
