Subject: repairing early HP calcs

I dont own any. But according to a recent Circuit Cellar article, early ics
can be easy to implement in a FPGA. Dont have the issue in front of me, but
the guy needed to mimic if you will a crt controller.
Therefore could the chips used in the early HPs (maybe up to and including
the 41 series?) be readily emulated by an FPGA?
