MEMORY CARD WITH DRAM I.C.'S ON P.C.B.

These printed circuit boards ,were made by Plessey in the 1980's and were never installed or used. We are selling them for the now rare semiconductors fitted on the board.

This type has:
 
84 x N.E.C. D4164C-3 (Full part number is UPD4164C-3)

These are 64k x 1 bit early DRAM memory chips, slow - 300nSec access time, 16 Pin DIL, 

The 4164 were a generic dynamic memory chip of the era, used in many early personal computers made by Commodore, Sinclair and Apple etc, these are all date code 1985.

The legs have not been cropped, so when desoldered from the board will be perfect chips.


 These boards are new unused and came to us many years ago directly from the Plessey manufacturing site, so the components on them are also perfect and original.

Priced and supplied each x1 board.
