<pre class="k9mail"><div dir="auto">Thanks,Alan. I feared that would be the answer. Everything going PDF, online and eBook. This is one of the things I'm really trying to get away from. I don't want to have to be always connected to the internet for every facet of life. Having said that, I checked on some of the transistors in my collection and they were largely designed in the 60s. I bought a copy of The Transistor and Diode Data Book for Design Engineers by Texas Instruments. I suppose that if that proves insufficient I should maybe go ahead with printing spec sheets for all the stuff I have and putting it in my portable hanging file box or get myself some kind of eink ereader to read the PDFs. <br><br>Rhys Sage<br><br></div></pre></blockquote></div></body></html>
