These are the devices I want - mostly transistors from the 1950's and integrated circuits from the early 1960's. I particularly want the types in bold type. Ideally I want several of each type - if you have any at all, please contact me and I'll make you an offer for them. Condition is not important - used examples are fine. I especially like examples on circuit cards.
