<br/>I think everything talked about makes sense to me ....as steampunk does include an earlier computer era to it .  Also steam ...hydraulics ...pumps ...gears ....all acceptable . I would thing the base electric would be here as well but just getting off the ground . Photography would exists ...crude movies ...I have put in a telecam type phone system in the Pleasure Dome .   Indeed computers and others would be more of a larger scale to achieve things ...nothing like microchips are around .<br/><br/>As far as music is concerned ....I think most styles would fit in ...I left the century kind of blank ....as in my mind this is just an alter universe .  So conceiving it is the 20th century or so is acceptable ..though they just rather stuck in an advanced Victorian like era .  That is my image of it anyways .
