Next best thing would be to find an EFIS sim that stil has round dial ASI and leave it in a ‘dumbed down’ state, i.e. don’t use any of the map functions, just compass rose.
When flying early 200 series, for six month recurrency we even went as far as to use an EFIS 300 with auto throttle and FMS de selected and derated the thrust to typical JT8 numbers. It was not ideal, but better than travelling half way around the world to find a real 200 box. We did the initial type rating and every second check in the approved 200 sim, but practically it made little difference that could not be covered during line training.
The clockwork 300 is not all that different to the early EFIS bird.
