Stack of Ferrite cores
Other nos on object: none
Inscription: "Mullard Type AW 3968, Serial No 14271"
Description: Five square ferrite cores held between metal plates, threaded screws at each corner. Much peripheral wiring remains.
DW:This is a group of magnetic core planes which are stacked together to form basically a magnetic core store. Again the number of wires coming off is fairly small so the electronics required was not enormous. These memories persisted for decades because they were reliable, fairly fast and exceptionally reliable by standards of the previous memories.
Q: When do they date from?
DW: I don't know. I was looking for the manufacturers name - I couldn't even find that but there is a number on it somewhere. They were manufactured in the Far East in large quantities. H167, I have no idea who made it. But this was made by Mullard, in Redhill, presumably.
