Tektronix sold Smalltalk workstations [1], you could run Lisp on them as well. You may have been able to run Smalltalk-80 on a Xerox Daybreak which was a fair bit faster than an Alto.
The first JIT was written by L Peter Deutsch for Smalltalk targeting the 68020.
I've been looking for one of these for years. Dont think ive ever seen one for sale. Sadly my retrocimputing days (especially for such rare and likely expensive machines) is about over. I've met people willing to strike me good deals on lisp machines, but these are just a bit too obscure perhaps.
