The reason the LISP chip based systems died is because general purpose
CPUs caught up with the speed of the LISP chips. So your Forth chip
would be unbelievably powerful initially, but not for as long as you
thought it would be.
I still remember the first Symbolics system. At a time when IBM was
still peddling 8088 based machines, Symbolics was using 68000s as IO
processors.

The Amiga's a could choice. It had "unbelievably powerful" graphics
when it first came out. But the general-purpose boards SVGA boards
eventually blew it away. Customized chips can't match the development
pace of high-volume hardware.
I was one of the Amiga faithful. Eventually, the (lack of) speed of
Python and similar tools drove me to switch to Unix (FreeBSD, to be
exact). I've got a CDROM somewhere that has all my Amiga data on it,
along with a copy of UAE. The box that replaced the Amiga ran the
Amiga Emulator at about 50% of the Amiga it replaced. And ran python
code *much* faster than the A3000.
