These printed circuit boards ,were made by Plessey in the 1990'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 Hitachi  HM51256LP-15

These are 256k x 1 bit early DRAM memory chips, 150nSec access time, 16 Pin DIL, 

The 41256 were a generic dynamic memory chip of the era, used in many early personal computers made by Commodore, Sinclair and Apple etc, these are mainly date code 1988.

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.
