If you want to see a tiny implementation then look for the PDP-1
implementation done by L Pete
David...where did you use Lisp on a B6700?
Bill Gord and I wrote the first INTERLISP interpreter for the B6700 back
around
1974-1975, on a DARPA contract, at UCSD. (At the start, it was to
implement BBNLISP,
but the name changed during the project :)

OK, it was some time ago, it well could be a Challenge L. it was a big box,
and was powered by a big 28 V power supply. (Or, was it a 48 V supply?)
Jon
It should be 48v. A 9uish VME style card cage. The Challenge XL / Full
rack Onyx and the Onyx / Challenge L should all share the same memory

Thanks for that bit of historical information. Things always make more sense in
context. When I learned lisp on a B6700 it was hard to understand and harder to
program. With this bit of context lisp now makes a lot more sense, and looking
back if I knew this then I’m sure I would have grasped th

I’d like to create a Tandy 150 replica one day since there are no known
examples in existence. It was based on the Naked Mini-4 system. These boards
seem to be an earlier CA product but I’m not sure. Anyone here know for
certain?

I have a Naked Mini, where are you located?
I couldn't see your images.. not sure if my vcfed account is still good.
So I don't know what you have.
