[1000mp] Need Help with MP Mod

[Joe Staples]

Tod,

Well I thought I'd examined that sucker top, bottom and sideways ... but 
I'll have another go at it.  I was expecting that the "top piece" would 
"overhang" the main body of the connector just enough to allow a sharp edge 
tool to lift it up.  But maybe it's flush and it only shows when there is a 
slight upward force on the ribbon cable itself.

Obviously "zero-force insertion" has it's limitations.

Again, many thanks.

Joe, W5ASP
