Source for 2.54mm 40-pin connector shells

Yup - and others as well - although seemingly not on the same board type, though. Pretty much all the 40-pin connectors I can see here (one a large range of board types) have Berg on them (although it seems DEC was making the part themselves under license, because all except one _also_ has a "|d|i|g|i|t|a|l|" logo on it too); there is one DuPont. The non-DEC Berg and the DuPont are absolutely identical except for the logo - and are on a pair of cards which use them for an over-the-back connection, so I suspect they are the same part, just re-labeled. The 50's a a mix of Berg and 3M. There are 20's which are Berg. The ones on the DLV11-J's (the one they gave the AMP part numbers for) aren't marked, nor are a number of the other small ones. Noel
