We are putting together a LISP-system on our Varian 74 mini-computer.
Our primary interest is to use the micro-programming capabilities 
of the machine to implement some of the most used parts of the 
LISP-system.

An implementation effort for LISP 1.5 is now underway on an 
Interdata 85. The interpreter is being written in PL/85, a locally 
developed structured assembly language. Though the implementation is 
being done on a model 85 it is compatible with other Interdata 16-bit 
processors.

The basic interpreter, storage management, and input/output packages are
 complete and we are currently extending our collection of SUBRs. 
We intend to implement the modified interpreter described in P.#Greussay, 
Iterative Interpretation of Tail-Recursive LISP Procedures, as well.
