There are two variants of HP9000/715: The older versions like the 715/33
have HIL only. The newer like the 714/64 have HIL and PS/2. You _need_
that breakout box for the later to connect any keyboard or mouse. It is

Depending on your personal preference FPGAs can be an annoying fight in
an obscure HDL with proprietary tools running on Window$, or it can
