Sorry the whole 'do something in a "Steam punk" way' is just silly.
a) Victorians, (as previously mentioned), had electricity.
b) Steam punk doesn't preclude the use of electricity, and if it does and isn't using 'magic', (maybe something like Space 1889), it just changes the laws of physics anyway.
c) Just use a large pin art board with appropriate mechanics if you want to go the whole 'not quite Steam Punk VDU route) - maybe just call it Georgian Punk, (but then they knew about electricity as well - but still burnt witches, so will slot in with the whole fanaticism thing).
