Intel D2102A 1024-bit (1024 x 1) NMOS Static RAM Chip w/Separate I/O and a Stepping Spec of S1298 in Gray Ceramic - Customer Sample - Extremely Rare

This Item is an Extremely Rare Intel  D2102A 1024-bit (1024 x 1) NMOS Static RAM w/Separate I/O and a Stepping Spec of S1298 in Gray Ceramic that is a Customer Sample as per the Photos.

The “CS” Marking on the Chip were Intel’s way of signifying that it was intended to be supplied to a Sales Person to give to a Prospective Customer as a Sample and as such only a few were marked in this way which makes them Extremely Rare.

The Intel 2102A was used in MITS Altair 8800 and IMSAI 8080 RAM boards 

This Intel D2102A Chip appears to have been manufactured during week 21 of 1977 in the Philippines.

I am unable to test this Chip for functionality so it is being sold for collection purposes only and as such has no warranty or guarantee of being functional.

I can assure any buyers that the prices for these vintage Chips will rise significantly over the coming years as they have done so over the past 30 years so it will be a good investment for them as the majority of the older chips have been scrapped for their gold content.
