random question. i was noticing after browsing some auctions that some Famicoms have a FF type logo like hte one on this atrocity and some do not.

when did the FF logo start showing up?

The famicom i bought at super potato a few years back doesent have it and its serial number is H11189445. i dont know what board revision it is because i never took it out of the plastic that super potato wrapped it in since i use the twin famicom i bought at the same time......god that was an expencive day out
