Magnetic core memory

[Geld Konig]

Hi,
I have several card from MDSA computer assembled in 1972 till 1975. Look the picture in site:
http://en.wikipedia.org/wiki/Core_memory. So, someone knows if are there some PM in this type of memory? I know that it make of ferrite and the connector? Some Pt or a PM alloy?

Aside from any gold plated edge connectors it may have (doubtful if any) there are probably no PMs on these types of boards. However, they are worth money as collectable computer history. You should be able to get $20-$100 on an online auction site, depending on what they are.
