I see no evidence for that. Lisp was a pain on tiny machines with bad user interface.

I had a Lisp on an Apple II. It was a useless toy. I was using UCSD Pascal and Modula 2 on it. Much better.
I had Cambridge Lisp on an Atari with 68k CPU. It was next to unusable due to frequent crashes on calling FFI functions.
The first good Lisp implementation I got was MacScheme on the Mac and then the breakthrough was Macintosh Common Lisp from Coral Software.

There were articles for example in the Byte magazine. Lisp simply was a bad fit to tiny machines. Lisp wasn't very efficient for small memory. Maybe with lots of work implementing a tiny Lisp in assembler. But who would have paid for it? People need to eat. The tiny Lisp for the Apple II was not usable, due to the lack of useful programming environment.

At least there were people willing to pay for it.
