What's missing is enough of my free time to dig through a 42-page thread.
Fair enough. But I gave you a link to a two page thread where all the relevant information was in the first half of the first page.
Calm down dude.
I'm calm, just confused, like many others here. I see you writing posts then almost immediately deleting them, it only adds to the confusion.

Anyway, here's the available Block Erupter a.k.a. ASICMINER information.

Update

Chip Specification
Technology Summary:
  130 nm
  1 Ploy
  6 Metal
  1 Top Metal
  Logic Process
Core Voltage: 1.2 V
I/O Voltage: 3.3 V
Core Frequency: 335 MHz
Core Frequency Range: 255-378 MHz
PLL Multiplier: 28
Power Consumption: 4.2 J/GHash
Number of Pads: 40
  22 Data
  18 Power
Package Type: QFN40
Packaged Chip Size: 6 mm x 6 mm
Our chips
Generation 1: Block Eruptor. 130nm with 6-8J/GH. Each chip's rated frequency is 336MHz at 1.05V. It translates to 336MH/s because it does one hash per cycle. The chips work stable and well at 392MH/s at 1.15V. Further overclocking needs proper handling of heat and power supply.

There are still no definite information about the die size. There are two posts that predate the tape-out.
Hashrate: 1.25GH/s per chip
Area: 17.5mm^2 per chip
Power Consumption: 13.3W
Hashrate: 1.00GH/s per chip
Area: 21.7mm^2 per chip
Power Consumption: 8.23W

I'm also positive that friedcat made other posts that he subsequently deleted, at least one in direct response to my post. It must have been commercially sensitive at that time.
