Anyone interested in a group purchase of MCM68766 chips?

Rumor has it that Wolfe, Julian may have mentioned these words:

I have a metric buttload of these suckers at home... those and the 
MCM68764's ( I have more '64s, but out of almost 10Kg of 'em, I'm sure I 
could find more than enough '66s ;-)

There's one caveat: There in Panasonic HHC carriers, with a decoupling cap 
on the power pins already. So, to use them in a standard DIP socket, you'd 
need to unwrap the pins from the carrier & desolder the cap. It needs to be 
done carefully, but certainly doable - I used a few on a CoCo1 - I 
'unwrapped' 8 chips one time, and 7 survived no problem.

>Unfortunately the places that sell them are asking for a $150-200 minimum

That's way too much... I'm cheap (at least that's what my wife says.)
;-) If you want *me* to extract & erase the suckers, I won't be quite so 
cheap, but certainly not near that pricetag.

How many do you actually need?
