I'm looking for the source code to "An M6800 LISP Interpreter" which
was published in August 1979 Byte Magazine's Nybbles Library as BYTE
document number 112. The code accompanied an article titled "The Design
of an M6800 LISP Interpreter" by S. Tucker Taft.

Can someone tell me if these old Nybbles Library programs are still
available? Are they archived such that I can ftp them? Can they be accessed
through BIX? Can I access BIX from the internet?

I would actually prefer the source to a (free) 68HC11 Lisp, if anyone can
direct me to one. While I believe that I can translate a 6800 assembler
program into 6811 assembler without too much trouble, it would be a lot easier
if I can find an interpreter already in 68HC11 assembler.

I want to implement a _very_ small Lisp interpreter on a Motorola 68HC11
processor with 32K RAM. The 68HC11 is on a MIT 6.270 robot board, and
I would like to do high-level A.I. type reasoning in Lisp, and link low-level
Lisp functions to assembly language drivers for motor control and sensors.

Please reply to me at watts@pat.mdc.com.
