I remember back in the mid 1980s, Apple and Texas Instruments collaborated
to build a hybrid dual-processor machine. It had a standard Motorola
68000 CPU like the Macintosh, plus a custom TI processor that executed
Lisp code in hardware. I'm told that the reason they never sold was that
the Lisp machine was considerably slower than the software Lisp solution
of the time.
On the other hand, there were Forth enthusiasts who hacked their
Macintoshes with Forth chips, and they went like a rocket.
