[sci.electronics] Early semiconductors wanted

awylie@pyr1.cs.ucl.ac.uk (03/25/88)

Hello,
      I collect early semiconductor devices - transistors and diodes. If
you think you might have something of interest in your junk box, please
have a look and tell me if you find anything that is on this list. I will
pay postage and a (small) cash price for any that I want. The earlier the
device, the more I want it!

                WANTED LIST OF EARLY SEMICONDUCTORS     A.WYLIE  March 1988

NOTE - it is not necessary for these devices to be unused or even working,
       however it IS important that they are manufacturers' originals, and
       not unbranded copies. The presence of the manufacturer's name or
       logo guarantees this, but some of the very earliest types do not
       have these markings. If in doubt, ask me.
