 |
|
I have had these laying around for a while and finally got to take a look at them.
They were remarked (repainted) and I was very curious as to why, so I scraped some paint, and stuck them on the scope.
It seems some mix-ups occured in the marking stage of assembly
4x National MM2708Q Remarked from a Rev B part to a Rev C
2x Motorola MCM2708C Remarked from a MCM2708BJBC Mil-spec part Motorola 2708 die
SOLD OUTx National MM2708Q Remarked from a MM2716Q (though the die is a 2708)
I only obviously scraped one each so maybe the one you get will be different but I think they will be the same (scraped ones I'm keeping, yours will be complete with mystery paint intact)
$1 each for these odd-balls
