Exact weight of the following consoles: SS, TFC, FC, FDS, SMIII

[layzee]

This might seem like a strange thing to ask for but for anyone that has a digital scale, could you please tell me the weight of the following gaming consoles (that you have)? Preferably with the metric system (i.e. grams, kilos)

Sega Saturn (any region should be fine, but preferably a Japanese one)
Nintendo Twin Famicom
Nintendo Famicom
Nintendo Famicom Disk System
Sega Mark III (Japanese Master System)

I need only the weight of the main console units, not the controllers etc.

Thanks.
