Concidering how much things have progressed since then, I would think only the outside shell would be as original spec,.
the command and service module was prolly 16k pre 286 computer technology, although I believe it was the first vehicle to utilise fly by wire.
I thought Dick Rutan had the brief to design a lifeboat for the ISS, I have seen a clip of his vehicle, looks like a very small lifting body with a para wing deploying in the lower atmosphere.
Rutan usualy does good work.
