I thought the CEM chips were made with Hans Camenzinds 700 series arrays. No?
They're still available from Diodes Inc.

I looked into this in 2005 through Zetex and Device Engineering 
Incorporated http://www.deiaz.com/quick_data_sheet.htm.
I can't remember the pricing now but it was not outrageous, 10's of 
thousands, not hundreds, but more than we were going to spend.
