Thanks! I didn't actually build it myself but a professor and other student were also involved. When I joined the project the decision was already made: the professor wanted to use APL and we were using an old CPU architecture book as reference that used APL (Gerritt A. Blaauw, Frederick P. Brooks Jr. Frend, Computer Architecture: Concepts and Evolution 1st Edition).

We almost got the PDP-11 working albeit some extensions like floating point arithmetic.
