response was abrupt, but Ive been watching you trying to sell these chips on ebay, with the word 'rare' used in your description.
My point is that they are a common enough chip without adding your 256 chip find to them.
They are also not the same chips Ed Hertel has on his website.
I have other color combinations of these also. Im not convinced any attribution so far made is correct.
While you are of course free to charge whatever price you like (although I dont somehow think you are going to get $11.66 x 256) you word your description as though you have a positive identification for them whereas to my knowledge none exists.
Thats why I made my point.
