The Ware for August 2020 is shown below.
While sending me an unrelated photo that I will feature in a future Name that Ware, David Willmore nerd-sniped me with this incidental photo. It is as of yet unidentified, but as far as I could tell it’s from a short-lived family of 1969-era Texas Instruments “DRA” — a Discretionary Route Array. Basically a wafer-scale bipolar gate array (back when “wafer-scale” meant one 1.5″ wafer — hence the circular boss in the middle of the package), which could run at speeds of up to 10MHz. For example, the DRA-2003 was a dual 501-bit shift register, and cost $390 back then in 100-249 unit quantities (around $2,800 inflation-adjusted). As an interesting side note, the rule-of-thumb pricing for a single processed 12″ wafer today is … about $3,000. That’s Moore’s Law for you: 50 years got us roughly a billion times more transistors on a single wafer of 64x the area for about the same cost.
I couldn’t find anything on this specific part number (DRA-2009E), so I figured why not turn it over to Name that Ware to see if anyone could come up with more details, about the logic family itself, or ideally about the specific part number shown here.
