Intel 1702A 2048-bit (256 x 8) EPROM in Gray Ceramic - No "C" Prefix - Customer Sample - Extremley Rare

This Item is an Extremely Rare Intel 1702A  2048-bit (256 x 8) EPROM in Gray Ceramic that is a Customer Sample with No "C" Prefix as per the Photos.

The “CS” Markings on the Front of the Chip were Intel’s way of signifying that they were intended to be supplied to their Sales People to give to Prospective Customers as a Sample and as such only a few were marked in this way which makes them Extremely Rare.

The intel 1702A was released by Intel during the 4th Quarter of 1972.
The 1702A is packaged in a 24-pin dual in-line package with a transparent lid. 
The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. 
A new pattern can then be written into the device.

This Intel 1702A Chip appears to have been manufactured during Week 27 of 1977 in Malaysia.

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.
