QRP semiconductor pin-out sheet?

Is it just me or do you also have to search the web quite frequently to confirm the pin-outs of devices you've used time and time again?  I need to do this for LM386, 2N3819, IRF510 and the 2N3904/6 almost every time I get them out of the drawers just to be sure. "Senior moments" I hear you say!

Does anyone know of a simple (all in one place) "crib sheet" that I could download giving the pin-outs of the common devices we frequently use in QRP projects?

Plessey reborn as UK's newest semiconductor firm

Many of us remember the Plessey name from the range of RF ICs it made back in the 1980s e.g. the SL640, SL641 and the SL6440. In their day they were ahead of the time. Many an SSB transceiver was built around these ICs. Well, Electronics Weekly reports Plessey is back.
"Plessey Semiconductors, one of the most renowned names in the UK’s semiconductor history, has been relaunched as a chip business operating from the original Plessey CMOS fab at Roborough in Plymouth.
Plessey Semiconductors has been created out of Plus Semi, a company set up to acquire the manufacturing facilities of two former Plessey fabs in Swindon and Roborough."
Electronics Weekly is available online and is well worth checking.
