According to the latest update from BFL_Jody, they've shipped most orders through the end of July 2012. Looking the the unofficial order queue at
http://bfl.ptz.ro/ they show about 250 Jalapanos delivered. If only ~50% of people who ordered Jalapenos entered their information there (which seems a safe assumption judging by the gaps in order numbers), then around 500 units were delivered. At 5Gh each, that would add ~2.5Th to the network.
Of course, I'm making some big assumptions based on incomplete data, so I could be way off.
Aren't you making data from your ass? According to their official support forums they've shipped 35 units last month. They never ever shipped anything before that so I don't understand that year 2012 in your post
As for that, they should have had several
wafers in initial batch which could be several
tens of thousands chips according to yeld (which is reported a very good). Last time I have checked, there have been way more than 100000 orders. So even if they shipped 500 someday, that is only tiny fraction of what they promised and even tinier of what ppl ordered.
